Chapada das Mesas National Park, National park in Maranhão, Brazil.

Chapada das Mesas National Park is a protected area in Maranhão known for its table-shaped plateaus surrounded by steep sandstone walls. The landscape features deep canyons, caves, and cascading waterfalls scattered throughout its Cerrado environment.

The park was created in 2005 to protect remaining Cerrado landscape from destruction caused by charcoal production and farming. This federal effort aimed to save one of the region's most threatened natural environments.

The park's name comes from its plateaus, whose sandstone walls resemble stone tables. Outside the park, the Morro das Figuras holds rock carvings that visitors reach on a trek; the surrounding Chapada das Mesas region also draws visitors to its waterfalls, canyons and trails.

The park itself is not open to visitors; the waterfalls and trails lie outside its boundaries on modified or private land. Access to São Romão and Prata waterfalls requires local guides and 4x4 vehicles. The Pedra Caída complex, a private 12,000-hectare area, has a cable car, heliport, and activities such as rappelling and zip-lining.

The park contains more than 400 natural water springs that emerge from the sandstone, creating small oases throughout the landscape. These springs are vital for the wildlife and plants living here, and they reveal how the geology of the plateau works.
