Núcleo Jequitibá serves as a primary access point to the Parque Estadual dos Três Picos, the largest state park in Rio de Janeiro, covering over 65,000 hectares. This administrative unit is situated at the base of the Serra dos Órgãos mountain range within the municipality of Cachoeiras de Macacu. The area features a transition zone of Atlantic Forest known for its high biodiversity and numerous waterfalls. Visitors utilize this sector as a base for trailheads leading into the high-altitude terrain of the park. The topography is defined by jagged granite peaks, which give the park its name. The site includes specialized conservation infrastructure for the protection of local flora and fauna. Hiking paths range from easily accessible nature walks to technical climbs. The area is integral to the preservation of the Macacu River watershed.
