Brazil Lake Cave

             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
