Your Lost Sea adventure begins with a guided tour of the caverns. This involves a 3/4-mile round-trip walk on wide sloping pathways. While touring the caverns and underground lake our guides will tell of the cavern's exciting and colorful history.
Over 50 smaller streams contained in 18+ miles of known passages combine in the main river passage to create America's longest navigable underground river. Living in the miles of flowing streams are rare blind cavefish and blind crayfish. Passengers on the custom electric tour boats can usually sight some of these unusual creatures as they float though the winding passages.
