If you’ve ever been intrigued by the subterranean world, plan a stay at Horse Cave KOA Holiday. It lies in the heart of one of the most significant cave regions on the planet. Beneath the area’s rumpled hills, eons of dripping & flowing waters have worn through the limestone bedrock, creating a maze of underground rooms, rivers & sinkholes. Nearby Mammoth Cave Nat’l Park preserves the world’s largest known cave system. Sign on for a tour for an introduction to this geological wonder. For an adventure, try the belly-crawling 6-hour Wild Cave Tour. Cleanup is easy at KOA, with its hot showers & laundry. Camping Cabins, shady Pull-Thru RV Sites, pool, mini golf & a playground make this a relaxing base. In fall, the trees reward you with glorious color.
