Welcome to Mammoth Cave National Park, home to the world's longest known cave system. Before you embark on your underground adventure, here are some helpful things to know before your cave tour. We highly recommend reserving your tour in advance @recreation.gov. There you can choose from a variety of tours based on distance, time, and difficulty. Be prepared for stairs. Many of our tours require climbing and descending several sets of stairs. Make sure to know what to expect on your tour. Some cave trails can be uneven. Wear sturdy shoes and watch your step on the rugged pathways. Some areas of the cave are tight and have low ceiling. You may need to duck or walk single file on your tour. It's all part of the underground experience. Cave temperatures are cool, averaging around 54°F. It's a good idea to bring a light jacket. Lighting in the cave is dim. Be aware if you have difficulty seeing in low light. Some tours require a short bus ride to different cave entrances. Make sure you're ready to board with your guide when your tour is ready to leave. All tours except the self-guided discovery Tour are led by a knowledgeable park ranger.
Make sure to follow your guide and stay with your group. Arrive at least 30 minutes before your tour to pick up your tickets and prepare for your tour at the visitor center. Only service animals are allowed on cave tours. You cannot bring weapons, flash photography back child carriers or large backpacks. We are excited to see you on your next mammoth cave adventure!

Several unpaved trails and service roads are available in the park for cyclists with mountain bikes. Trails not listed below are closed to bicycle use. Remember that when on trails shared by hikers and horses, cyclists are required to yield to the other trail users.
Mammoth Cave Railroad Bike and Hike Trail
9 miles (14.4 km)
Originally opened in 1886 the Mammoth Cave Railroad brought early tourists to Mammoth Cave and other neighboring caves in the area. The train line continued its service for 45 years and made its final run on August 1, 1931. Today, a portion of the path of the former Mammoth Cave Railroad has been converted into a 9-mile hike and bike trail. This trail can be accessed from Park City, KY, several points along Mammoth Cave Parkway, and the park’s visitor center area. Along the trail, cyclists and hikers can stop at historic sites, interpretive waysides, and scenic overlooks. While on the Trail:
Dismount and walk your bicycle at all road crossings.
Be aware of hills and steep grades. Walk your bicycle when signs instruct you to do so.
Keep your children near at all times.
Observe warning signs.
Bicycle helmets are recommended for all riders.
Remain on the trail and always practice Leave No Trace.
Big Hollow Trail
9.1 miles (14.6 km) North Loop: 5.3 miles (8.5 km) South Loop: 3.7 miles (5.9 km)
Connector Trail from the Big Hollow Trailhead to the Maple Springs Trailhead
1 mile (1.6 km)
The Big Hollow Trail Loop Trails and Connector Trail offer over 10 miles of single track mountain bike trail that winds through dense woodlands and rocky outcroppings. The trail can be accessed from the trailhead within Maple Springs Campground.

Part of the U.S. Bicycle Route System
Mammoth Cave National Park is included in two U.S. Bicycle Routes (USBRS) that connect urban and rural communities across the United States via signed roads and trails.
TransAmerica Bicycle Route, USBR 76
The TransAmerica Bicycle Trail was designated in 1982 and spans the nation from coast to coast. On its 4,228-mile (6804.3 km) journey, the trail passes through the states of Oregon, Idaho, Montana, Wyoming, Colorado, Kansas, Missouri, Illinois, Kentucky, and Virginia. Along the way riders can take several spur routs to scenic destinations like Mammoth Cave National Park.
Cave Country Bicycle Route, USBR 23
Designated in 2019, the Cave Country Bike Route connects USBR 76 to the Tennessee border, through Kentucky’s Cave Region. The 109-mile (175.4 km) route takes riders through Mammoth Cave National Park and connects to small towns and historic sites.
What is an e-bike? The term “e-bike” means a two or three-wheeled cycle with fully operable pedals and an electric motor of less than 750 watts (1 HP). Where can I ride my e-bike in the park? E-bikes are allowed in the park where traditional bicycles are allowed. Can I ride my e-bike by using only the electric motor? Using the electric motor to move an e-bike without pedaling is prohibited on bike trails and service roads. The sole use of the electric motor is allowed only where motor vehicle use by the public is allowed, i.e. paved roadways. Learn more about e-bikes in national parks .
Whether riding on one of the parks scenic roadways or on an off-road trail, your safety is your responsibility. Make your visit more enjoyable by learning about safety while in the park.
Children ages 12 and under are required to wear a personal flotation device (PFD or life jacket) at all times while onboard a watercraft in Mammoth Cave National Park. It is important that PFDs are properly fitted and US Coast Guard approved.
Over 30 miles of the Green and Nolin Rivers trace through the Mammoth Cave National Park and offer a wealth of recreational opportunities. Angle for muskellunge, bluegill, catfish, bass, perch, crappie, and other game fish. Canoe or kayak the rivers looking for wildlife, springs and river bluffs. Camp on islands, in the floodplain, or by the river at the Houchin Ferry Campground . These rivers offer something for everyone.
About the Rivers
Kentucky's First National Water Trail
The rivers inside of the park are part of the Green and Nolin Rivers Blueway , a National Water Trail encompassing 36 miles of navigable waterway and 7 public access sites. This designation actively supports public access for safe river recreational use, promotes stewardship, and connects communities and visitors to enjoyment and appreciation of the overall health of the river system and surrounding lands.
Planning Your River Trip
Always wear a life jacket. Personal flotation devices (PFDs/life jacket) are encouraged for all river users and required to be worn by children ages 12 and under at all times while on rivers inside of Mammoth Cave National Parks. It is important that your PFD is properly fitted, and US Coast Guard approved. Federal and state law requires a Type I, II, or III PFD for each person onboard a watercraft.
Let someone know your plan. You should always leave a float plan with family/friends and inform them of your departure and return. Do not forget to inform them when you return so an unnecessary search is not started.
Leave alcohol at home. Alcohol is prohibited on the rivers inside the park.
Know the water level and weather forecast. River use is prohibited when river levels are at or exceed 20 feet on the park's water level gauges.
More information on boating and watersports throughout the national park system is available for you to review, including safety and trip planning tips.
River Access Points
Within the park there are three river access points accessible by car: Dennison Ferry, Green River Ferry, and Houchin Ferry. All of these sites are located on the south side of the Green River. Outside of the park on the Nolin River is the Tailwater Recreation Area.
Dennison Ferry consists of a wooden canoe and kayak ramp with a series of concrete stairs to the water.
Green River Ferry consists of a wooden canoe and kayak ramp with a concrete staircase to the water and an auto ferry ramp that doubles as a launch site for motorboats.
Houchin Ferry consist of a temporary canoe and kayak launch ramp. This launch site is often very muddy, please use caution.
Tailwater Recreation Area consists of a paved boat ramp to access the Nolin River.
Dennison Ferry to Green River Ferry

Current and Forecasted Water Levels on the Green River
In cooperation with the US Geological Survey, the park maintains a water level monitoring station on the Green River inside the park boundary. The National Weather Service in Louisville, in coordination with the Ohio River Forecast Center, maintains a Daily Forecast for the Green River at Mammoth Cave National Park . Flood Warnings will be issued on the National Weather Service site when water levels are expected to reach or exceed the Minor Flood Stage level of 32 feet. The following flood stages have been established at Mammoth Cave, KY:
Moderate: 52 ft.
Lock and Dam 6 Rapids
Class 2 rapids have developed on the Green River at the former site of Lock and Dam 6 at Mile Marker 182. The rapids area starts just past the park's western boundary and before you reach the Brownsville Boat Ramp. Please adjust your plans accordingly.
Swimming in park waters is not recommended. At normal stage, the Green River flows at a relatively brisk 4.3 knots, about 5 miles per hour, which is too strong to swim against. There is no designated swimming area in the park and no lifeguards on duty. Wading in shallow water can also pull you off of your feet. Stay far enough back from moving water so that an accidental trip or slip on wet rocks will not cause you to fall into the current and be swept away.
Swimming, wading, or bathing within 200 feet (61 m) of the Green River Ferry crossing is prohibited.
The use of tubes, inflatable pool toys, or pool rafts to float the rivers is prohibited.
What comes to mind when you think about fishing? Patience, relaxation, challenge, and memories? You may find all that and a sense of stewardship, conservation, and preservation. Take some time to explore our fishing information and learn what the park has to offer as well as your responsibilities before casting a line or flicking a fly into the water.
No fishing license or permit is required within the boundary of Mammoth Cave National Park.
Fishing Regulations
In addition to the rules outlined in 36 CFR 2.3 , 36 CFR 7.36 , and the Superintendent’s Compendium , the following fishing regulations apply within the boundaries of Mammoth Cave National Park.
Prohibited Fishing Methods
Do Not Collect Mussels
To learn more about fishing regulations the National Park Service, visit the Fish & Fishing website.
Fish Consumption Advisories in National Park Waters
The Environmental Protection Agency, states, territories, and tribes provide advice on fish and shellfish caught in the waters in their jurisdiction to help people make informed decisions about eating fish. Advisories are recommendations to limit your consumption of, or avoid eating entirely, certain species of fish or shellfish from specific bodies of water due to chemical or biological contamination. Fish is part of a healthy balanced diet, but eating wild fish and shellfish caught in park waters is not risk free. Parks are “islands”, but the much larger “ocean” that surrounds them affects the natural resources inside a park. Other aquatic toxins are the result of natural biological processes. Also, chemical contaminants that originate outside of park boundaries can come into parks. Mercury is an example of a toxin originating outside a park that can find its way into a park. Mercury exists naturally in some rocks, including coal. When power plants burn coal, mercury can travel in the air long distances before falling to the ground, usually in low concentrations. Once on the ground, microorganisms can change this elemental mercury to methyl mercury. This type of mercury can build up in animal tissues, and it can increase in concentration to harmful levels. This high concentration can occur in large predatory fish - those often pursued and eaten by anglers. Studies have shown that fish in some National Park System waters have mercury levels that may be a concern to people who regularly eat a lot of fish.
Mammoth Cave National Park Fish Consumption Advisories
All Kentucky waters are under a consumption advisory for mercury. More information about fish consumption advisories throughout Kentucky are available from the Kentucky Department of Fish & Wildlife Resources . To learn more about this topic, the National Park Service maintains information about Fish Consumption Advisories and Mercury and Toxins in Nature .
Aquatic Invasive Species
Imagine your favorite fishing spot and the wonderful memories. Things may look fine but underneath the surface there is a serious threat. Everything you remembered is now cemented together in a sharp, smelly mess. Invaders have wiped out the fish species you used to catch. Aquatic invasive species are not native to an ecosystem. Their introduction can cause harm to the economy, the environment, or to human health. Aquatic invasive species are a growing risk to parks and their values. In the United States alone, there are more than 250 non-native aquatic species. For many centuries, humans have contributed to spreading non-native species around the globe. You can make a difference. To learn more about Aquatic Invasive Species in the National Park Service, visit their Fish & Fishing website.
How You Can Help – Stop Aquatic Hitchhikers
You can help stop the spread of aquatic invasive species in park waters and other waterways by following the simple guidelines outlined by the campaign to Stop Aquatic Hitchhikers!
Fishing Throughout the National Park Service
We invite you to visit the Fish and Fishing website for more information about fish and fishing in the National Park Service. You will learn about conservation, different fish species, and parks that offer fishing.
Current River Level and Forecast for the Green River
Mammoth Cave National Park is an exceptional destination for anyone who loves to see the world from the back of a horse. Riders will find miles of wooded backcountry trails suitable for many skills and ages. The trails range from wide, smooth dirt paths that two riders can travel together, to daring, single file, ridgeline trails.
Bringing your horse to the park
60 miles of backcountry trails north of the Green River are open for horseback riding.
Trailer Parking
Day-use horseback riders can park trailers at the following trailheads on the north side of the park:
First Creek Trailhead
Lincoln Trailhead
Maple Springs Trailhead
Maple Springs Campground, across the road from bulletin board
Temple Hill Trailhead
Vehicle size limit on the Green River Ferry
The Green River Ferry is the most direct route from the visitor center to the park’s north side backcountry trials and the Maple Springs Campground. The ferry has a 8-ton load limit. However, some vehicles (i.e. long horse trailers) cannot be ferried solely because of the length or ground clearance. The ferry is open daily from 6:00 AM - 9:55 PM (except when closed for repairs or during hazardous river conditions). Alternate routes via state and county roads are available and may be more practical for trailers.
Guided Horseback Riding
Commercially guided horseback riding is a great way to explore the park without needing to bring your own horse. Suitable for new riders and beginners, it may even nurture a life-long passion! Guided outings in the park are only available through authorized operators with a commercial use authorization from the National Park Service.

Trail Rules and Stewardship
Horseback riders can provide an excellent example to all visitors by following the Seven Leave No Trace Principles as well as these park rules:
Horseback riding is prohibited on all park roads.
When hikers and horses meet, horses must be slowed to a walk and hikers should remain quiet.
Stay on marked trails only. Do not shortcut trails or follow social trails - this erodes and damages trails.
Trails can become muddy in some locations after rain. To preserve the trail surface avoid riding after recent rainstorms or when trails are excessively wet.
Always hitch horses more than 100 feet away from designated campsites, trails or water sources.
Never tie horses to trees. Always cross-tie horses between trees.
Leave no litter in the backcountry. Remember: Take only memories; leave only footprints.
Backcountry Safety
Make sure your ride in the park is a happy one. Learn more about park safety and how to ride and hike smart before your trip in the park.

How to Get Started
While in the Park
Start by downloading the official NPS mobile app on your smartphone and navigate to the Mammoth Cave National Park page. Using the NPS app, you can follow along to the various Beneath Your Feet locations as you walk around the visitor center area. Your smartphone camera application can also be used to scan the QR Code on the Beneath Your Feet wayside signs to open the web link to watch videos and learn more about the cave passage below.
The virtual tour information along with video recordings are available on the links below, so you can explore Mammoth Cave from the comfort of your home.
The free, official NPS app includes an interactive Beneath Your Feet, under Self-Guided Tours.
“How did you discover the above-ground locations…?”
Park scientists use radio telemetry to map out where important parts of the cave are in relation to the locations directly above ground. Also known as a “cave radio,” it is one of many fascinating ways that scientists create surveys and maps of caves . A surveyor inside the cave creates a magnetic signal while surveyors on the surface use a receiver to pick up the frequency. This allows the above-ground team to find the location directly above the cave passage. This information helps draw us closer to the below ground world and lets us know what is truly beneath our feet.
Since prehistoric times, humans have looked up at the night sky and pondered the wonders of the universe. People have used the stars and planets to navigate, keep track of time, and to connect with other cultures. Regardless of your reason, Mammoth Cave National Park provides an ideal place for stargazing. After a day of hiking, kayaking and exploring the cave, the fun doesn’t have to stop there, because half the park is after dark!
Tips for Stargazing in the Park
A red light works best. Flashlights with red lights will allow you to navigate walkways in the dark without disturbing your night vision.
Find a wide-open area. The grass fields and parking lots near the visitor center can make a great spot to have a wide view of the sky. Tall trees and hills may block your view.
Avoid areas with artificial light sources. You’ll want to find a place that you can step away from car headlights and lights from buildings, to get the best experience.
You don’t need a telescope. While a telescope can be a great tool to see smaller night sky objects, they aren’t always necessary. Many planets and constellations can be seen with the naked eye. For an extra boost, try using a pair of binoculars.
Stargaze with a Ranger
Ranger-led stargazing programs are offered throughout the year to provide an opportunity to experience unfettered views of the starry night and evoke a new appreciation for the park’s dark sky environment. Attendees get to view planets and other night sky delights through telescopes provided by the park. Check our park calendar to find available programs on the dates of your visit.
Junior Ranger Night Explorer
Explore the starry side of your national parks and become a Junior Ranger Night Explorer .
Can you Spot the Station?
The International Space Station can often be seen passing overhead by the watchful stargazer. To the naked eye the station usually looks like a bright white dot moving very quickly as it passes without changing direction. It is often the brightest object in the night sky second only to the moon.
Preserving Dark Skies
The National Park Service is working to help protect our night skies and reconnect the world to the stars above.

Protect Your Park, Protect Yourself
Mammoth Cave National Park is a special place that is open for everyone. For over two centuries people from around the world have been visiting this place to reconnect with the natural world and the history of the area. Protect yourself and the sights you plan to enjoy by following a few simple rules:
Follow the Leave No Trace Seven Principals. By following the Leave No Trace Seven Principles , you will help protect yourself and the park for years to come.
Never approach animals. The animals in the park are wild and unpredictable, no matter how calm they appear to be.
Never feed wildlife. Animals that become dependent on human food may become aggressive toward people and have to be killed. Keep all food, garbage, or other smelly items packed away when not in use.
Stay on boardwalks and trails. Poison ivy, ticks, and venomous snakes are present in the park. Keep your children close and don’t let them run.
Never park in the road or block traffic. Use pullouts to watch wildlife and let other cars pass.
We can’t guarantee your safety in the park, but these concepts will help you avoid the most common accidents. See below for more great advice, and be sure to review our Laws & Policies .
Your safety depends on your own good judgement, adequate preparation, and knowing what to do in an emergency. Backcountry hikers, bikers, and horseback riders should be in good physical condition and be prepared with proper equipment and the knowledge of how to use it for a safe trip. Your safety is your responsibility. Learn more about how to hike smart when using the trails in the park.
Spending time on the Green and Nolin Rivers inside the park has become a popular activity. These dynamic river systems have many hazards and have the potential to cause serious injury or even death. When recreating in the park remember, your safety, is your responsibility. Learn more about safety and regulations on the rivers .
Heat Related Illness
High temperatures and the risk of heat illness can happen rapidly during the summer months when temperatures can exceed 90ºF (32ºC). Be prepared for heat and humidity while recreating in the park. Always carry and drink plenty of water, as well as eat salty snacks, as excessive sweating can diminish the body’s sodium levels.
Bats and People
Less than 1% of bats in nature have rabies, but bats that act strangely or contact humans are up to 10 times more likely to have rabies. Humans can get rabies by exposure to bat saliva through a bite or scratch. Rabies is 100% preventable in humans with proper medical care, but it's almost always fatal if untreated. Rabies is fatal to bats, too. If you see a dead bat or a bat that is behaving strangely, such as being aggressive, lying on the ground, flying near, or making contact with people, tell a park ranger right away, and do not touch it. More information about rabies is available from the NPS Biological Resource Division.
Ticks, Snakes, and Poison Ivy
Ticks can be prevalent throughout the park and there is a risk of tick-borne illness if one bites you. It is important to take precautions and to be aware of the risks. When in tick habitat:
Wear light-colored clothing, long sleeves, and long pants, with pant legs tucked into socks and shirts tucked into pants. Consider wearing gaiters as well.
Do frequent tick checks of yourself and any children or pets with you.
Always check for ticks after any outdoor activity, both at the end of the day and the next morning.
Consider using chemical applications. 0.5% Permethrin insecticide applied to clothing is effective in reducing tick bites; however, when used improperly it can create negative health effects. DEET repellent has only limited effectiveness against ticks (less than a couple of hours). Picaridin is another repellent option that will not ruin synthetic fabrics or their water-repellent finishes. Always use and store chemicals according to the manufacturers' instructions.
Be alert for venomous snakes. Copperheads and rattlesnakes are generally found on land but may sometimes be seen in the water. Use ordinary precautions: wear shoes and always carry a flashlight after dusk. If you see a snake, leave it alone! All animals in the park are protected by law.
Poison ivy can be found throughout the park and can grow as a shrub or vine. The leaves are red in early spring, shiny green in summer, and an attractive red or orange in the fall. Each leaf consists of three leaflets.
Most people are sensitive in varying degrees to the oils of this plant, which makes skin itch, blister, and swell.
Avoid contact with all parts of the plant. If exposed, wash the affected skin with soap and water as soon as possible. It takes several minutes for the oils to penetrate the skin.
Do not burn campfire deadwood that is entangled with poison ivy leaves or vines. Soot from the fire can carry the sap through the air, and cause serious distress in the eyes, nose, and throat.
Your Safety in the Cave
When on a tour in the cave there are several considerations to keep in mind help protect yourself and the cave resources:
Watch your step while touring the cave. The trails can be uneven and in some places are wet.
Use the handrails.
Watch your head in areas with low ceilings.
Stay on the trail at all times. The trails are clearly marked.
Do not sit, step, or climb on rocks in the cave.
The cave is dimly lit. Lighting of the trail will vary, so be careful when walking in areas with low light.
Always stay with the tour group.
All children under 16 must be within arm's reach of a parent or adult chaperone throughout the tour.
Stop walking when taking pictures or using video cameras. Using cameras while walking is hazardous and can lead to serious personal injury, injury to others, or damage to the cave.
Flash photography is not allowed in the cave. Flashes from cameras can temporarily blind and disorient people.
Do not remove anything from the cave.
Do not leave trash or anything else behind.
Do not write or mark on the cave walls.
Avoid touching the cave or leaning against the walls. The oil in your skin can permanently stain and discolor the rocks and formations.
No tobacco can be used in the cave, including vape pens and e-cigarettes
No gum, food, or drink is allowed in the cave, except for clear bottled water.

In 2004, the National Oceanic and Atmospheric Administration installed a climate observing station inside Mammoth Cave National Park as part of the U.S. Climate Reference Network (USCRN). The USCRN's primary goal is to provide long-term temperature, precipitation, and soil moisture and temperature observations that are of high quality and are taken in stable settings. The station within the park is officially known as KY Bowling Green 21 NNE.
Kentucky has a moderate climate with warm, yet moist conditions. Summers average in the high 80s; winters average in the low 40s. Southern Kentucky, where Mammoth Cave is located, receives the highest average precipitation for the state, about 50 inches per year, mostly in spring. Winter can bring mild to moderate snow and ice. Storms happen year-round, and can include tornadoes and flooding in low-lying areas, but severe weather is infrequent. The temperature deep in the cave is a constant 54°F (12°C). The USCRN Program provides online access to near-real-time observations for KY Bowling Green 21 NNE . To learn more about the USCRN’s nationwide collaboration with NPS, see NPS and USCRN: A Collaboration for the Ages .
Weather-Ready Nation
Mammoth Cave National Park is a Weather-Ready Nation (WRN) Ambassador. The WRN initiative is a National Oceanic and Atmospheric Administration (NOAA) program to formally recognize NOAA partners who are improving the nation's readiness against extreme weather, water, and climate events.
