Pacaás Novos National Park is a protected area in the state of Rondônia in western Brazil that conserves montane and lowland Amazonian ecosystems. The park protects sections of the Pacaás Novos mountain range and associated rivers and forests.

The park contains rainforest, river valleys and upland habitats that support regional biodiversity and watershed protection. Recreational and scientific visits are possible but the area is remote and infrastructure is limited.

The park was established to conserve natural ecosystems of the Pacaás Novos region and to maintain water resources and biodiversity in Rondônia. Its boundaries and management reflect national conservation objectives for Amazonian and transitional environments.

Pacaás Novos National Park lies within northern Rondônia in western Brazil, in a landscape of forested mountains and river systems. The nearest major regional centres are those in Rondônia state; access typically requires travel by road and river into remote parts of the state.

How to Get to Pacaás Novos National Park #

Access is generally from the state of Rondônia. The park’s remoteness means most visitors start in Porto Velho and travel by road (often long, unpaved stretches) or arrange river transport and local guides from towns such as Guajará-Mirim or Ji-Paraná. Expect multi-day journeys into park sectors.

Tips for Visiting Pacaás Novos National Park #

  • Hire a local guide from the nearest town who knows seasonal river levels and the park's informal trails.
  • Pack insect repellent and a light mosquito net for overnight stays - parts of the park are mosquito-heavy at dusk.
  • Bring cash and fuel: services are sparse; expect long drives over unpaved roads.
