Morro do Diabo, Mountain summit in Teodoro Sampaio, Brazil
Morro do Diabo is a mountain summit rising 600 meters above sea level within the Atlantic Forest region of São Paulo state. This natural formation serves as the focal point of a large protected area containing preserved forest sections.
The area began as a forest reserve in 1941 and became a state park in 1986. This transformation brought protection to thousands of hectares of remaining Atlantic Forest in the region.
The hill is tied to local stories about indigenous burial grounds, which shaped the tales explaining its name, Devil's Hill. This connection to the past remains part of how visitors understand and experience the place today.
Access is through marked hiking trails that offer varying difficulty levels and pass through the forest landscape. Visitors should arrive early to have enough time for exploration and to return before darkness falls.
The mountain is home to one of the largest free populations of the black lion tamarin, a primate species that is highly endangered worldwide. Spotting this rare animal can be an unexpected experience for nature-focused visitors in this forest area.
