Zoológico de Piedra [1]: There’s no question that a mountainside zoo where the life-size critters are hewn from boulders is one of a kind.
La Farola [2]: A steep mountain road snaking into the pine-clad Sierra Cristal offers fabulous vistas, but watch those bends.
Museo Arqueológico Cueva del Paraíso [3]: This fascinating albeit simple museum of Taíno culture is set in hillside funerary caverns with pre-Columbian skeletons still in situ.
Parque Natural Duaba and El Yunque [4]: Rugged mountain terrain provides a challenging but rewarding hike to the top of the famous rock formation El Yunque, with incredible views as an added bonus.
Parque Nacional Alejandro de Humboldt [5]: Wilderness supreme! This park provides great opportunities for bird-watching and hiking into the mountains, and manatees can be spotted along the shore.
