La Cueva del Indio, the Cave of the Indian, is located near Arecibo on Puerto Rico’s north coast. La Cueva del Indio gets its name from the great number of engravings, known as petroglyphs, found on the cave’s walls. The engravings are believed to be the work of the Taino, the pre-Columbian inhabitants of the island. Archaeologists have studied the cave, providing evidence that it contains one of the largest concentrations of petroglyphs in Puerto Rico. This rich legacy from the area’s indigenous cultures earned the cave its protected status as a Natural Reserve, managed by the Puerto Rico Department of Natural and Environmental Resources.
