Cave of the Indian is crossed by the San Juan River (navigable). Visitors enter the cave through a narrow opening and follow a well-beaten, dimly lighted stone trail for 255 meters (842 feet), narrowing and widening until you reach a high-ceilinged grotto and an underground river. You board a boat here for a short cruise (300 meters [990 feet]) past illuminated stalagmites. The boat takes you out of the cave through a narrow, vine-draped opening in the rock.

Guanahacabibes peninsula is at the western end of Pinar del Rio. In this national park, considered a Reserve of the Biosphere, there is a surprising variety of landscapes and ecosystems: evergreen forests, mangrove, beach coasts with swampy vegetation, high reef coasts and sandy coasts with a vegetation of sea grapes, palm trees and mastic. The pine forests are indigenous and vast, and the grassy plains hold the richest fauna in these ecosystems. The fauna is rich on aquatic birds, mollusks and reptiles. Here is Maria la Gorda Scuba Diving Center, famous for its transparent marine landscapes, where it is possible to find multiple species of corals, the biggest colony of black coral in the Cuban seas.

This area contains the oldest rocks in the country, and many fossils of marine reptiles, mollusks and fish from the Jurassic Period have been found here.
