Planning multi-day hike in Chapada Diamantina brazil

Hi there fellow travelers , so I’m planing to go in 2 weeks to Chapada Diamantina and I’ve heard that there is a few multi day hikes that you can do.

We have a few questions, what multi-day hikes you recommend we have around 10 days to spend there. Also, are the hikes dangerous? I mean from dangerous animals like snakes and spiders (I guess there is but is the likelihood high?) to bad trail conditions or lack of signals to find the path.

Lastly, are there places to do camping and also fresh water to filtrate? We are planing to bring out tent and gear to this trip

My girlfriend and me we both speak Portuguese, also we have some experience in multi-day hikes, wild camping and navigating with the GPS (we use all trails and wikiloc).

Thank everyone for your help!!
