Underground boat and flashlight group tours
Take an arranged group below ground for a boat ride and flashlight exploration
The Lost Sea / Craighead Caverns
The Lost Sea advertises an advance-reserved Flashlight Tour for groups of 25 or more: a cavern walk and underground boat ride, extended into an undeveloped cave section. This is a location-bound group adventure, not a wedding venue or exclusive cave buyout.
Current location note / listed area: Sweetwater, Tennessee · arranged onsite group tours
Private-celebration acceptance requires inquiry. The site currently warns of drought-related low water while stating tours remain open; confirm the boat route, date, group minimum, steep terrain, accessibility and required flashlights directly. The separate crawling/overnight Wild Cave program is not included.
