Gran Caverna de Santo Tomás

The Gran Caverna de Santo Tomás are situated about 10 miles (16km) west of Viñales. With more than 29 miles (46km) of underground galleries spanning eight different levels, it's Cuba's largest cave system and one of the most important in South America. Fantastical limestone formations, glittering stalactites and stalagmites, underground lakes and vast caverns reveal themselves by the light of headlamps. Amateur spelunkers will probably be limited to just two levels, with entrances to them semi-hidden on a forested slope overlooking the valley and providing wonderful vantage points for views and photographs.
Address: El Moncada, 11 miles (17km) west of Vinales village
