Fodor's Expert Review Cachoeira da Fumaça

One of the most popular hikes in the national park leads to the country's tallest waterfall, 1,312-foot Cachoeira da Fumaça (Smoke Waterfall). Most of the falling water evaporates before reaching the ground, hence the odd name. A 6-kilometer (3-mile) path from the village of Caeté-Açú takes you to the canyon's rim, where you can marvel at the smoke rising from above. Visiting the waterfall from Lençóis takes the best part of the day and should be done with a guide.
