Tumucumaque National Park, National park in Amapá and Pará, Brazil

Tumucumaque National Park is a protected forest reserve in Brazil's Amazon region spanning across Amapá and Pará states. The land is covered in thick tropical forest with many rivers running through it, creating a water-rich landscape.

The park was created by presidential decree on August 22, 2002, after collaboration with the WWF, covering about 3,867,000 hectares. Its management plan was published on March 10, 2010, and it is part of the Amapá Biodiversity Corridor, created in 2003.

The park itself is uninhabited; the nearest communities are outside its boundaries. At Vila Brasil, on the right bank of the Oiapoque opposite the French Guianese indigenous community of Camopi, residents are mostly traders who provide services to indigenous people from across the border, and small hotels let visitors observe this exchange.

The park is best explored by boat, as rivers form the main routes through the territory. Visitors should prepare for humid, hot conditions and plan to travel with experienced guides familiar with the area.

The park forms a transnational conservation area with French Guiana's protected forest park across the shared border. This cross-border connection creates one of the world's largest continuous protected rainforest regions.
