Pedra da Boca, Rock formation in Araruna, Brazil.

Pedra da Boca is a rock formation about 336 meters high in Pedra da Boca State Park, in Araruna, Paraíba. It is named for a cavity eroded into the rock that looks like a large open mouth. The surrounding area has trails used for hiking, climbing and rappelling.

The area has been inhabited by indigenous peoples for centuries, who left marks of their presence on the rocks. The site was later protected as a state park, transforming it into a place accessible to visitors for recreation and learning.

Indigenous peoples created rock paintings in the area, leaving traces of their presence and connection to these stone formations. Visitors can still see these markings on the rocks, which tell stories of the people who lived here centuries ago.

Wear comfortable hiking shoes and bring plenty of water since the trails have steep sections and the sun is strong in this region. Plan your visit for early morning or late afternoon to avoid the hottest part of the day, especially during drier months.

The main rock formation has a large cavity carved by erosion over centuries that resembles an open mouth in the mountainside. This distinctive hollow was created by water flowing through the stone, slowly shaping it into this unusual form.
