Home of the largest underground lake in the nation, the caverns include an extensive collection of anthodites (cave flowers). A guided walk to the bottom of the cave is capped off with a boat ride on the lake. The Lost Sea is a registered US Natural Landmark. The Wild Tour, an overnight caving tour for groups, is a favorite of scouts.
