Cool, damp air rises out of Mammoth Cave's historic entrance, a sinkhole that pulls you off the ridge and into stone passages that hold near 54 degrees while the woods above climb past 90. Ranger-led tours follow lantern-lit rooms, still pools, and an underground river for miles through the longest known cave system. Summer weekend and holiday tours sell out.
On the surface, when you come in from I-65 at exit 48, the Green River cuts through the park, and trails run the woods between the river and the cave. Tours run year-round, and fall is the easier window once the summer crowds thin.
Cave tours reserve through recreation.gov, and you lock a campsite in the same pass, before the van. Mammoth Cave Campground is the van overnight, 111 sites at $25 a night with a 38-foot cap, as of September 2026. Maple Springs is the smaller loop across the river, seven sites at $50, 40-foot max, and no sewer.
The Green River Ferry is running and limits vehicles to 16 feet and 12 tons. If you need more sleeping space than a van, a Bowling Green RV rental still fits the campground loops, but skip the ferry.
Barren River Lake State Resort Park
From the marina docks you look across about 10,000 acres of open water, then walk back to wooded shoreline sites. The park is near Lucas, southeast of Bowling Green. The campground has 101 hookup sites, a dump station, and showers, open mid-March through mid-November, so reserve it ahead.
Nolin Lake State Park is closer on the map, but its RV and electric sites are closed indefinitely after 2025 flood damage, as of September 2026. Tent camping, the swim beach, the boat ramp, and a 9.2-mile bike and hike trail stay open. A van that needs a hookup goes to Barren River.
National Corvette Museum
The Skydome holds rows of Corvettes under glass, some still crumpled and dust-caked from the 2014 sinkhole that opened under that floor. That hole swallowed eight cars, and some of them are back on display as they came up. The Motorsports Park next door is the track day after the museum.
Parking is day use only, and the museum does not offer camping. Sleep at Beech Bend in town, or at Mammoth Cave Campground if the next morning is a tour.
Beech Bend Park
Splash Lagoon's slides and lazy river run against a wooded bend of the Barren River, and on race night the NHRA dragstrip launches under the lights. The campground is the in-town base when you come in from I-65 at exit 28, 400-plus first-come sites with 30- and 50-amp hookups, open year-round. There's no reservation system, so a dragstrip weekend and a water-park weekend compete for the same vans and the same pads. If the loop is full, Mammoth Cave Campground is the overflow you should already have reserved.
Lost River Cave, also in town, sends a flat-bottom boat tour into a dark cave mouth on the underground river, walls close overhead. Give it a couple of hours, then come back to Beech Bend.
Red River Gorge, Natural Bridge, and Daniel Boone National Forest are covered on the Kentucky campervan page.
