Rio Puruba flows through Atlantic rainforest near Ubatuba before meeting the ocean at Praia do Puruba, located along the Rio-Santos highway past Itamambuca in the direction of Paraty. The river is clean and calm, making it well suited to stand-up paddleboarding and similar flatwater craft. The confluence with the sea creates a visually distinctive landscape, with green forested hills rising behind the beach and the river meeting the ocean at the shoreline.

Access involves taking a dirt road off the Rio-Santos highway, which passes through Atlantic rainforest before ending at a parking area at the river's edge. Paddlers should note that to reach the beach itself, crossing the river is necessary. Parking fees are typically 10 to 20 reais.

There are no facilities, kiosks, or amenities at the site, so paddlers should arrive self-sufficient with food, water, and any gear they require. While the river itself is calm, the adjacent ocean beach is subject to waves and current, and caution is warranted near the river mouth where conditions can change. The area receives relatively few visitors compared to more developed beaches in the Ubatuba region, and the surrounding rainforest setting remains largely undisturbed.
