Cachoeira Das Três Barras sits on the Rio Piabas, reached via a trailhead at the river bridge roughly 58 km from the center of Andaraí. The hike covers about 6. 5 km one way, rated moderate to advanced, and takes around 1.

5 hours — partly along the riverbed itself and partly descending the serra. The falls reward visitors with a striking visual and a deep swimming hole.

From here, an additional 20-minute walk leads to the nearby Cachoeira dos Cristais, a 110-meter waterfall whose name is said to come from the crystalline shimmer that sunlight produces on the quartzite bedrock when water levels are low.

The two waterfalls are commonly visited together as a single half-day outing in the Chapada Diamantina region.
