The western zone of Rio is the one with the most surface area, and the ample green sceneries are home to many challenging mountains and boulders, as well as rocks that can be playgrounds or exercise areas for beginners or advanced climbers.

Pico da Pedra Branca is the highest peak in the Pedra Branca state park, and also the highest peak in the city - Interestingly, this peak is taller than the second highest, the Tijuca Peak, by one solid 3 meter high boulder that locals joke to have been placed there on purpose.

Pico dos Quatro is a popular rock climbing spot, offering stunning views and the practicality of being relatively near the south and central zone - Its popularity among climbers derives from the multiple challenging ascent routes.
