Take a walk on the wild side... (São Paulo)

Anybody would be up to join a group of Rainforest visitors?! I’ve been taking small groups in short trips to Natural Reserves in São Paulo where we walk up along trails through the forest, observing and commenting the landscape and its biodiversity, taking pictures, etc. On the way up we normally plan to reach the waterfalls 'hidden' in the area, on the way down the reward for the trekkers would be reaching the beach, but what happens 'out of planning' usually are the best surprises... ;) you know what I mean?!
