One of my favorite hike so far.
Go to Vidigal with a taxi and you will see motos taxi next to the police station.
Take a moto taxi and ask him to drop you at the football field (5 rials). You will find the start of the hike easily just next to the field.
From there you can hike Dois Irmaos mountain…. amazing !
Monkeys on the hike 🙂
