Parque Estadual dos Três Picos is the largest state park in Rio de Janeiro, Brazil, offering rugged mountain terrain, rich Atlantic Forest ecosystems, and outstanding opportunities for hiking, climbing, and wildlife observation.
Parque Estadual dos Três Picos, established in 2002, spans approximately 46,350 hectares across the municipalities of Cachoeiras de Macacu, Guapimirim, Nova Friburgo, and Teresópolis in Rio de Janeiro state. The park is dominated by the Três Picos massif, with the highest peak reaching 2,316 meters, the tallest point in the Rio de Janeiro state. This rugged landscape consists of granite and gneiss formations surrounded by dense Atlantic Forest, one of the most endangered tropical forest biomes, home to diverse flora such as orchids, bromeliads, and rare hardwood trees, and fauna including endangered species like the muriqui (woolly spider monkey) and the ocelot. Visitors can explore well-marked trails that traverse valleys, waterfalls, natural pools, and mountain summits with panoramic views of the Serra do Mar mountain range. Rock climbing is a key activity, particularly on the challenging vertical faces of Três Picos. The park also plays a critical role in regional hydrological cycles by protecting sources of several rivers. Due to the park's mountainous terrain and protected status, it appeals to hikers and outdoor enthusiasts seeking remote wilderness experiences combined with opportunities for environmental education. Access points are found in several small towns bordering the park, each serving as gateways for different routes and levels of difficulty.
