Your Lost Sea adventure begins with a guided tour of the caverns. This involves a ¾ 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. They will also explain the fascinating geological development of the immense cavern rooms and rare formations. At the bottom of the cave you will take a boat ride on The Lost Sea, America’s Largest Underground Lake.
