Open to the public since 1930, the Lost River Caverns are part of a limestone cave system filled with stalactites, stalagmites, and beautiful crystal formations. Guided walking tours of the caves are offered all throughout the year. Tours take between 30 and 45 minutes, and they require navigating paved walkways and a handful of stairs.
After exploring the cave, make sure to leave some time to mine for gems at the Gem Mill, stroll along the property's 1800-foot nature trail, and enjoy a picnic lunch at one of the tables in the shady picnic grove.
