The waterfall is part of the Prumirim River, which flows directly into the nearby Prumirim Beach.
The rock face is naturally polished by water erosion, creating a series of tiered cascades that vary in depth.
It is a popular location for 'canyoning' activities due to the specific geological structure of the falls.
The site remains one of the few easily accessible waterfalls in the Ubatuba region that retains a direct visual connection to the coastal Atlantic Forest ecosystem.
Cachoeira do Prumirim is a tiered waterfall located in Ubatuba, Brazil, characterized by its series of natural rock slides and deep swimming pools. The site features multiple drops that culminate in a large, swimmable basin at the base. It is situated within the Atlantic Forest, providing significant natural shade along the riverbanks. Visitors frequently use the smoothed rock formations as natural water slides. Access involves a short walking path from the highway, transitioning through forest terrain. The water temperature is generally cool, sourced from the higher elevations of the Serra do Mar.

Wear water shoes with good grip, as the submerged rocks can be extremely slippery.
Bring mosquito repellent, as the surrounding dense Atlantic Forest environment attracts insects.
Visit on a weekday to avoid the significant crowds that gather during weekends and public holidays.
Do not attempt to climb the upper levels of the waterfall during or immediately after heavy rainfall due to the risk of flash floods.
Avoid using soap or shampoo in the waterfall pools to protect the water quality; remove all trash before departing.
