Bonito
The Formoso River runs through the Cerrado (the Brazilian Savannah) in the proximity of a city called Bonito, in the State of Mato Grosso do Sul, in Brazil. The rivers and the bodies of water around the Bonito area are the only places in South America where Anacondas can be found in crystal clear waters, and therefore diving with them is possible. Other places where they are found are marshes and rivers too murky and turbid to take a dive in.
End of July/beginning of August marks in that region the peak of the winter, the best time to dive with these majestic creatures. During this time the anacondas wake up from hibernation to shed their skin, feed and mate. The river water temperature is 22-24 degrees Celsius (72-75 Fahrenheit) year round and when during winter the air is generally cooler than the water the anacondas spend more time in the water.
