Bonito

Brazil's ecotourism capital: float-snorkel in crystal-clear rivers, visit the Blue Lake Cave and the Macaw Sinkhole.

Bonito lies in the Serra da Bodoquena in southwestern Mato Grosso do Sul, in Brazil's Center-West, about 300 km from the state capital, Campo Grande, with the Pantanal wetlands to the north. The ground beneath is a vast limestone karst; as water flows through it, calcium carbonate settles out and takes impurities with it, leaving rivers such as the Rio Sucuri and Rio da Prata as clear as an aquarium, with every fish and water plant in plain view. Brazil's Ministry of Tourism has repeatedly named it the best ecotourism destination in the country. Visiting works a little differently here: almost all attractions are on private ranches with daily visitor limits, and must be booked through licensed agencies in town and visited with a guide—you can't just show up. There are three core experiences. First, "flutuação" float-snorkeling: drift downstream in a life jacket and mask (Rio Sucuri, Rio da Prata, Nascente Azul and others). Second, caves, such as the Gruta do Lago Azul (Blue Lake Cave), the Gruta de São Miguel and the Abismo Anhumas, which requires a 72 m rappel. Third, waterfalls and birdwatching at sinkholes, such as the Boca da Onça waterfalls, Estância Mimosa and the Buraco das Araras (Macaw Sinkhole). Bonito can be visited year-round: the dry season (May–Sep) brings the clearest water and cooler temperatures, ideal for snorkeling; the rainy season (Dec–Mar) is hot, and occasional storms can briefly cloud the rivers, but the waterfalls are at their fullest. Jan–Feb and July, during Brazilian school holidays, are the busiest times, so book ahead. Getting there: Bonito has a small airport with direct flights from São Paulo in high season; more people fly to Campo Grande and take a bus or private transfer (about 4–5 hours). The town is small, with restaurants and agencies concentrated on Rua Coronel Pilad Rebuá. Plan to stay 4–5 days, doing one or two activities a day. Note: sunscreen and insect repellent are not allowed when snorkeling, and you must not stand on the riverbed; popular activities often need to be booked several weeks in advance; most sites are 20–60 km from town, so you'll need tour transport or a rental car.
