Bonito is the heart of eco-tourism in Brazil because it is famous for its natural beauty, prehistoric caves, waterfalls, and clear blue waters. One of the most beautiful is Blue Lake Cave (Gruta do Lago Azul). Amazingly, it is believed that no human set foot inside the cavern with the cobalt blue waters until 1924 when an Indian from the Terena tribe discovered it. That’s not to say nothing ventured down into the 328 feet (100 meters) deep cave, since massive mammals fossils from about 10,000 years ago were discovered by cave divers, bones such as those belonging to the Saber-tooth tiger and giant ground sloth. Because the water is so clear, it is hard to fathom that Blue Lake Cave is about 295 feet (90 meters) deep. Adventurers start with a hike through the forest, then go caving through a wide entrance that allows sunlight to illuminate the gorgeous blue waters as well as stalactites and stalagmites of all different sizes. Here’s a look at Bonito, Mato Grosso do Sul, Brazil and some of the extraordinary and unusual ecotourism adventures and true natural treasures including beautiful Blue Lake Cave. [25 Photos]

Waterfall in Bonito, Mato Grosso do Sul. Bonito is the heart of eco-tourism in Brazil. During the rainy season, from December to March, the vegetation is extremely green and provides plenty of food for the wildlife; the rivers are high and the waterfalls are abundant. Between May and August, there is much less rain so the waterfalls are somewhat less spectacular. Photo #3 by LNarimatsu
Wikipedia explained, “The Pantanal is an ecological paradise right in the heart of Brazil. It is the largest flooded lowland on the planet and the third largest environmental reserve in the world.” Mato Grosso do Sul is “famous for its natural beauty, and is a major destination for domestic and international tourism. The Pantanal lowlands cover 12 municipalities and presents an enormous variety of flora and fauna, with forests, natural sand banks, savannahs, open pasture, fields and bushes. The city Bonito, in the mountain of Bodoquena, has prehistoric caverns, natural rivers, waterfalls, swimming pools and the Blue Lake cavern. Photo #4 by Alicia Yo
Bonito is famous for it’s caving and river activities. “Snorkling in the Rio da Prata.” According to Wikipedia, “Bonito is in the middle of a region which is being discovered as ‘Caribe do Centro-Oeste’ (Caribbean of the Central-West) due to the unbelievable blue color of its waters. Owing to the enormous quantity of limestone in the ground, the water of these rivers passes through a real natural filter where impurities are deposited at the bottom of the river bed, leaving the rivers to be some of the clearest and most transparent in the world.” Photo #5 by Laurian

Blue Lake State Park is where the adventure begins to reach Gruta do Lago Azul or Blue Lake Cave: “The tour starts with a 10-minute walk to the entrance of the cave, which was discovered by a local Indian in 1924. In its interior, after descending 100 meters, it is possible to see the lake of crystal clear water and depth of approximately 90 meters, which makes it one of world’s biggest flooded caves.” Photo #8 by Jonas Henrique

The name Mato Grosso do Sul literally means ‘Thick Forest of the South’ in Portuguese, a name inherited from its northern neighbor state of Mato Grosso, of which it was part until the 1970s. It is not uncommon for people to mistakenly refer to Mato Grosso do Sul as simply ‘Mato Grosso’.” Blue Lake Cavern entrance. Photo #10 by O Fuji
