The wildlife here is a must,but the incidence of the "Coral" snake is a problem!
Considering this reptile is one of the most dangerous snakes in Brazil,I would recomend you to have long/strong boots for your trecks!!!
Here is this famous snake,the picture was taken in the museum,when it was in a glass cage!!!!
All the guys we asked before the trip didn't recomend us to visit the Park during the rain season!!
The best time is from August to November,when the rain is almost rare.
