Bonito: Brazil’s Natural Gem of Crystal-Clear Rivers and Hidden Caves

Bonito – which means “beautiful” in Portuguese – lives up to its name in every way. This small town in the Brazilian state of Mato Grosso do Sul has become a top destination for nature lovers and eco-adventurers. With transparent rivers, stunning limestone caves, vibrant wildlife, and one of the best eco-tourism models in the world, Bonito is a place where nature and responsible tourism go hand in hand. A must for your next Brazil vacation.
Where is Bonito, and what makes it special?
Bonito lies in southwest Brazil, about 300 km from Campo Grande and close to the famous Pantanal wetlands. It sits atop a limestone plateau that has been carved by water over thousands of years. The result? Underground rivers, dramatic caves, natural springs, and waterfalls – all in a remarkably preserved environment.
Why visit Bonito?
1. Crystal-Clear Waters
Bonito’s rivers are known for their exceptional clarity, thanks to the region’s limestone base. The natural filtration system means you can see up to 50 meters underwater. Snorkeling here is like swimming in an open-air aquarium – no walls, no tricks, just nature.
2. Model of Sustainable Tourism
Bonito is a global example of successful ecotourism. All activities are carefully regulated, group sizes are limited, and every tour must be pre-booked with a scheduled time slot. This protects the environment and ensures a personal, crowd-free experience.
3. Unique Biodiversity
Located between the Pantanal and the Cerrado (savannah), Bonito is home to an impressive mix of species. Spot toucans, macaws, capybaras, giant otters, and even tapirs – all in their natural habitat.
Top Activities in Bonito
Snorkeling in crystal-clear rivers

• Rio Sucuri: Considered one of the clearest rivers on Earth – a surreal experience.
Exploring the Gruta do Lago Azul (Blue Lake Cave)

Waterfalls and Natural Pools
Bonito has several nature reserves with trails, waterfalls, and natural swimming spots. Popular choices include Estância Mimosa and Parque das Cachoeiras – ideal for families and nature lovers.
Best time to visit
• Dry season (May to September): Best water visibility, ideal for snorkeling and hiking.
• Rainy season (December to March): Lush green surroundings and stronger waterfalls – but sometimes lower visibility in the water.
What to expect: Responsible tourism done right
Bonito’s success lies in its strict eco-guidelines:
• All activities must be pre-booked
• Visitor numbers are capped daily
• Local guides are well-trained in environmental education

This keeps the experience authentic, uncrowded, and respectful to nature.
