Welcome to Cuba’s largest cave system and the second-largest on the American continent. There are over 46km of galleries on eight levels, with a 1km section accessible to visitors. There’s no artificial lighting, but headlamps are provided for the 90-minute guided tour. Highlights include bats, stalagmites and stalactites, underground pools, interesting rock formations and a replica of an ancient native Indian mural.
Wear suitable shoes and be aware that the cave requires some steep climbs and scrambling over slippery rocks. Most people visit the cave on an organized trip from Viñales (CUC$20).
