The Grotto features chambers with ceilings reaching 35 feet, decorated by gypsum deposits and golden flowstone formations. These wild cave tours, designed to last between two and three hours, focus on the geology and fragile ecosystems of the subterranean environment. Guests will traverse both narrow passages and expansive rooms, occasionally spotting the small fish that inhabit the cave’s crystal-clear underground waters.

Jonathan Perez, the lead guide for TennTours, will oversee the expeditions to ensure safe navigation through the untouched passages. According to Anjan Ghosal, founder of Sojourn Lodging, this initiative aims to provide an immersive alternative to traditional mountain tourism by connecting guests directly to the region's natural history. Visitors staying at the resort will receive priority booking and discounted rates when the program officially launches later this year.
