Beyond Marina Chapelín, Varadero sprawls east like a displaced North American suburb with scrubby mangroves interspersed with megahotel complexes and the odd iron crane. Pass all this and 500m beyond the Club Amigo Varadero on the Autopista Sur, you'll find this cave, interesting for its 47 pre-Columbian drawings, discovered in a 300m recess in 1961.
The black-and-red drawings feature the same concentric circles seen in similar paintings on the Isla de la Juventud, perhaps a form of solar calendar. The cave was also used as a refuge by escaped slaves.
