Watch the sunlight bouncing off the water as it tumbles over Tres Tombos Waterfall. Look out for any rainbows that form in the mist.
Located in Feiticeira, this cascade of water is well worth including on your itinerary. But you'll find tons more to see in this area. Guaeca Beach, Feiticeira Beach, and Bonete Beach aren't too far away from Tres Tombos Waterfall.
