About Mammoth Cave Campground
Overview
Please review "Need to Know" for the campground and additional "Need to Know" information for individual sites.
Clicking on the site number link will provide more details about the site's conditions. Be sure to check the 'Need to Know' section for each site to gather additional information on specific conditions.
Mammoth Cave Campground offers campers a prime location to explore both the depths and surface treasures of Mammoth Cave National Park.
Mammoth Cave is an underground passageway with over 400 miles of naturally sculpted limestone and sandstone, making it the longest recorded cave system in the world. The grand-scale chambers and winding passageways were the inspiration for the park’s name.
The campground also serves as an entry point to 14 miles of hiking and biking trails, and is just a five-minute walk to the Visitor Center, where cave tours begin
All wheels must remain on the pavement within the campground, as varying conditions can cause muddy ruts and erosion.
Recreation
A must-do activity in the park is exploring Mammoth Cave. Walking tours of the caverns leave from the visitor center daily. There are also miles of bike trails and hiking trails within the park.
Facilities
The 109 primitive campsites are arranged around 4 paved loops, surrounded by fragrant trees. Fill and dump stations are located in the Camp Store parking lot.
Water and restrooms are conveniently located inside each loop, with the park’s Visitor Center just a short five-minute walk away.
Restroom Locations:
Restrooms are situated within each loop.
Loop A: Restroom near the main campground road.
Loop B: Two restrooms located near Site 12 and Site 51.
Loop C: One restroom located near Site 82.
Loop D: One restroom located near Site 108.
Additional amenities; coin-operated showers are available adjacent to the campground, behind the Caver's Camp Store, next to the Post Office. Please inquire at the Camp Store for current shower fees.
Natural Features
The campground is tucked inside Mammoth Cave National Park, which boasts scenic valleys along the Green River. The river is within walking distance of the camp, and the hilly Kentucky countryside expands beyond the valley.
Deer and turkeys commonly stroll around the campground, so visitors are likely to see them grazing in the early morning and at dusk.
Nearby Attractions
Nearly 30 miles of the Green and Nolin rivers offer canoeing and boating through the park. Commercial outfitters outside the park rent canoes, kayaks and safety equipment. Most trails north of the Green River are open for horseback riding. Commercial liveries outside the park rent horses and some may provide organized excursions.

How current is this availability data?
