Bonito — Crystal-Clear Rivers
★★★ Bonito — Snorkeling in the Natural Aquarium
Bonito in the state of Mato Grosso do Sul is Brazil's capital of ecotourism — and a natural wonder like no other. The rivers here are so crystal clear that you can see the fish 30–50 meters away. The reason: The limestone in the region naturally filters the water, making it crystal clear.
Top Experiences
- Rio da Prata: The ultimate Bonito experience. Snorkeling in a crystal-clear river, surrounded by hundreds of tropical fish (Dourados, Pacus, Curimbatás) that come so close you could touch them. Drift in the water for 2–3 hours — like in a natural aquarium. From 350 BRL (€58).
- Gruta do Lago Azul: A huge limestone cave with a deep blue underground lake. In December/January, sunlight streams through the entrance, illuminating the water in an unreal blue. From 80 BRL (€13).
- Rio Sucuri: Even clearer than the Rio da Prata — visibility up to 50 meters. Shorter snorkeling route, but even more impressive. From 300 BRL (€50).
- Abismo Anhumas: Rappel 72 meters deep into a cave, then dive or snorkel in an underground lake with stalactites and stalagmites. A unique experience for adventurers. From 1,000 BRL (€165). Prior training session required.
- Boca da Onça: The highest waterfall in the state (156 m) amidst rainforest. Hike to 8 waterfalls with natural pools for swimming.
