The Tumucumaque Mountains National Park is situated in the Amazon Rainforest in the Brazilian states of Amapá and Pará. It is bordered to the north by French Guiana and Suriname.

Tumucumaque was declared a national park on August 23, 2002, by the Government of Brazil, after collaboration with the WWF. It is part of the Amapá Biodiversity Corridor, created in 2003. The conservation unit is supported by the Amazon Region Protected Areas Program. Its Management Plan was published on March 10, 2010.

Tumucumaque Mountains National Park has an area of more than 38,800 square kilometers, making it the world’s largest tropical forest national park and larger than Belgium. This area even reaches 59,000 square kilometers when including the bordering Guiana Amazonian Park, a national park in French Guiana. This combination of protected areas is still smaller than the three national parks system in the Brazil-Venezuelan border, where the Parima-Tapirapeco, Serranía de la Neblina, and Pico da Neblina national parks have a combined area of over 73,000 square kilometers.

Tourism in the Park takes place in two different sectors: Amapari Sector and Oiapoque Sector.

In Amaparí Sector, the Park is accessed by Serra do Navio city (most common) or by a community in Pedra Branca do Amapari (usually in the summer). The trip is made by the Amapari River, using aluminum boats (90 km from Serra do Navio) to the park’s rustic base, where it is possible to stay in a camping structure adapted to Amazonian conditions (hammocks) and do activities such as trails, bathing in rivers and animal and plants watching.

In Oiapoque Sector, you can camp at Cachoeira do Anotaie, which is located on the Anotaie River, a tributary of the Oiapoque River. This waterfall is 40 km from the city of Oiapoque, on a trip using aluminum boats. There is also the possibility to visit Vila Brasil, a community located on the right bank of the Oiapoque River and located in front of the French-Guyanese indigenous community of Camopi. In this location, there are small hotels and it is possible to understand its socio-cultural context, where the residents, mostly traders, provide services to the indigenous people of the neighboring country.
