Recreation
Picnicking, enjoying the outdoors, and exploring the caves are of primary interest to visitors. The site has trailheads to the Green River Bluffs Trail and the Dixon Cave Trail. Both hiking trails are about a mile long.
Facilities
The picnic shelters are across from the Visitor Center parking lot, nestled in the Picnic Area. Each shelter is equipped to accommodate up to 60 people. Choose from the enclosed shelter or the open shelters, and enjoy the grassy surrounding area as well.
Natural Features
The picnic shelters are surrounded by oak, elm, and maple trees in the Green River Valley. The park sits above the labyrinth of underground caves and extends out over rolling hill country.
Nearby Attractions
The Green River is where anglers can fish for perch, bass and bluegills, and where kayakers can paddle past lush, tree-lined banks. Any part of Mammoth Cave National Park's 52,800 acres is worth exploring through trails or scenic drives.
