3 Best Sights in Jayuya, The North Coast and the Cordillera Central

The main attraction of the 7,000-acre "Black Bull" State Forest is the island's crowning glory: 4,398-foot Cerro de Punta. Toro Negro also has the island's highest lake, Lago Guineo, as well as an impressive waterfall, the 200-foot Salto de Doña Juana. The best place to start is at the ranger station on Route 143. Ask the friendly staffers for a map; the trails—like the one that leads from the ranger station to an observation tower with views of the northern and southern sides of the island—are not always well marked. There are more trails east of the ranger station, at the Area Recreacional Doña Juana. Keep an eye out for exotic birds, such as the Guadalupe woodpecker. The reserve also contains a huge swimming pool (often out of service) built into a mountainside. Note that some trails have not been fully cleared or restored following Hurricane Maria's devastation in 2017.

This huge boulder with a handful of highly visible Taíno petroglyphs is located in a stream among several other large rocks. There are several viewing areas and a shady spot for a picnic lunch. Don't worry: the boulder in the parking lot painted a lurid shade of blue is not La Piedra Escrita. Also remember wet rocks are slippery, so for your own safety do not jump from the stones or climb them after dark.
