Hidden River Cave Entrance – Horse Cave – Kentucky
The entrance to Hidden River Cave, once known as Horse Cave, and the cave the city derives its name from. At different times the cave was the city’s water supply, source of electricity and a dumping ground for waste. Tours were offered from 1912-1943, until the increasing pollution and World War II led to a halt in tourism. And it wasn’t for another 50 years that interest in the cave returned, and the American Cave Conservation Association (ACCA) took on the task of rehabilitating the cave, In 1992 the first phase of the current museum and cave tours was developed. And today thousands of visitors come to the cave to enjoy the interesting geology of the karst regions of Kentucky. The cave boasts the longest underground suspension bridge in a cave system.
