Linking together Brazil's two largest cities, Rio de Janeiro and São Paulo, lays the Serra da Bocaina mountain range. In the Tupi-Guarani language, Bocaina means "paths to the heights". Since the early seventies over 110 thousand hectares of the region has become a stunning national park famous for its gloriously lush Atlantic Rainforest.

This stunning trekking challenge is on a mixture of jeep tracks, narrow jungle trails and on the principal path through the park, which is known as the Trilha do Oura, or the Gold Trail which was originally built by slaves to transport gold to the coast. The area is one of a real wilderness with spectacular biodiversity, rocky outcrop mountains of over 2000m with hidden waterfalls and rainforest pools. At night we sleep in basic homes listening to the sound of the forest.

Our challenge finishes at the famous carnival city of Rio de Janeiro for a celebration party not to be forgotten!
