The waterfall is the primary source for the Jaguari River, a key component of the Cantareira System supplying water to the São Paulo metropolitan area.
The name 'dos Pretos' historically refers to the 19th-century Quilombo settlements established in the surrounding Serra da Mantiqueira region.
The total height of 154 meters is achieved through a series of cascades rather than a single vertical drop.
The location is a recognized center for adventure sports including rappelling and canyoning.
Cachoeira dos Pretos is a 154-meter-high waterfall located in the Mantiqueira Mountains within the municipality of Joanópolis, São Paulo. The waterfall is formed by the Pretos River, which originates in the Extrema region of Minas Gerais. The site serves as a municipal park, featuring a large, accessible swimming hole at its base. The waterfall is known for being one of the tallest in the state of São Paulo. Visitors can access the base via a relatively flat trail, though the full extent of the complex includes multiple viewpoints and upper sections. The area surrounding the waterfall is part of a local ecological park management plan to preserve the riparian vegetation.
The main viewing platform located near the base provides the most stable vantage point for capturing the full scale of the drop.
Wear water shoes or sturdy sandals, as the rocks near the swimming hole can be extremely slippery.
Bring a waterproof bag for electronic devices if you plan to get close to the base, as the spray is significant.
Pack insect repellent, as the humid, forested environment attracts mosquitoes.
Do not attempt to climb the rocks adjacent to the main waterfall, as they are unstable and pose a high risk of falling.
Respect the park's leave-no-trace policy by carrying out all trash; swimming is permitted only in designated areas.
