Make sure you bring a camera to capture the flowing cascades of Blue Lagoon Waterfall. If it's raging, you may be able to feel the mist on your face.
When you've finished up at this Capitólio cascade of water, why not check out Capitólio Canyons Lookout, Furnas Dam, and Capivara Waterfall? They're near Blue Lagoon Waterfall and also a hit with many travelers.
