Chapada Diamantina National Park is a nature reserve in eastern Brazil. At its northern edge, Paí Inácio Hill has panoramic views. Waterfalls include Fumaça, which evaporates in mist before reaching the ground, and Devil’s Pool, with black water, both in the north. The vast sandstone-and-quartz Lapão Cave is nearby. Lençois and Mucugê, old diamond-mining towns within the park, have colonial architecture.
