Pick-up and transfer from Petropolis Terminal Station or your lodging we'll start our expedition on Serra dos Órgãos.

The first day of Petrópolis Teresópolis crossing is the most demanding. During the 7 km up to Castelos do Açu mountain shelter we gain approximately 1100 meters of altitude. The trail to Açu mountain goes through a dense forest and with a strong ascent to Pedra do Queijo viewpoint. Then the trail gets a little less steep until arriving at Ajax viewpoint, which has natural water supply. After Ajax, we need to face the section considered the most difficult of the ascent to the Açu castles: the Isabeloca mountain. This ascent is named after an alleged passage of Princess Isabel on the spot. Once Isabeloca is over, we’ll cross the Chapadão do Açu, a counterfort, before arriving at the Açu castles.

The view from the top of Açu castles closes the first day with a golden key. From there it is possible to see all Rio de Janeiro and Guanabara Bay in addition to the entire mountain range of Serra dos Órgãos. Overnight mode: Camping at Açú Castles Peak
