Cachoeira do Tobogã is a natural waterfall and rock slide located near Paraty, a colonial town roughly 250 km from Rio de Janeiro.

The main attraction is a broad, smooth rock face worn by flowing water that visitors use as a natural toboggan — sliding down into the pool below.

The waterfall itself is modest in height, but the experience of riding the slick rock draws independent travelers, backpackers, and guided jeep-tour groups alike.

A short walk upstream leads to a second waterfall known as Poco de Tarzan (Tarzan Pit), which features a rope bridge and a small café.

The site is reachable by local bus from Paraty's bus terminal; buses run toward Penha roughly every hour, and the ride takes about 20 minutes. Visitors should ask the driver to stop at the "cascata."
