Located on the eastern coast of the state of Maranhão by the banks of the Preguiças River, the park embraces the municipalities of Humberto de Campos, Primeira Cruz, Santo Amaro and Barreirinhas, the latest serving as the main jumping off point into the protected park.
There are several regular bus/truck routes between Barreirinhas and São Luís, Brazil (Maranhão's capital), a distance of about 260 km. There are also air taxis from São Luís to Barreirinhas. The Rio Preguiças river connects the park to Atins, a small town at the southern edge of the park. The most important access roads near the park are BR-135, BR-222, MA-404, and MA-225.
The National Park is quite extensive and has no direct access roads. Because of the nature of the park's protected status, most vehicles are not permitted access. Entrance to the park is made exclusively by 4-wheel drive trucks. Escorted trekking trips and tours are offered by various companies including Adventure Life, Bespoke Brazil, and Pantanal Adventures.
