Backpacking in Serra do Divisor
👌 Worth visitingnational park ranked #21
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

Serra do Divisor gives you Amazon rainforest with almost no other tourists, which is the whole point. The park sits in the far west of Brazil, in Acre, against the Peruvian border. Getting here is slow and some trails need a guide, so skip it if you want tidy infrastructure. Come for the jungle-covered ridges and river travel. I stepped off the boat in Mâncio Lima and heard only frogs and a distant outboard motor. A first day could mean a river ride, a village lunch and a short forest walk.

✨ Why go?
Ranked #21 national park in Brazil
Why visitors keep coming back

Serra do Divisor National Park suits travelers who like their wilderness unpolished. Almost nobody else is here, so you deal directly with local boatmen and community guides instead of joining a package group. The reasons to make the effort are the Rio Moa and Juruá Valley river routes, the sandstone ridges of the Serra do Divisor range along the Peruvian border, and the chance to see rare Amazon wildlife in forest that has barely been touched. Plan for slow transport and simple lodging, and you will have the quiet side of the Amazon.

💡 HighlightsDon't-miss highlights and experiences

  1. Serra do Divisor ridgeline: The jagged forested range on the Peruvian border is the park's signature, a rare rise above the flat Amazon basin and the sight most people come for.
  2. Rio Moa: Boats follow this dark river through flooded forest, with birds and caimans along the banks. It is the main way into the park's interior.
  3. Rio Juruá: The big river of the region carries the boat traffic and shows riverside life, with stilt houses and fishing canoes.
  4. Mâncio Lima and Cruzeiro do Sul riverfront: The gateway towns give you river markets and fish stalls, plus the chance to hire boats and guides.
  5. Primate and bird watching: The forest holds monkeys, macaws and toucans, and at dawn from a canoe you hear them before you see them.
  6. Riverside communities: Visiting small settlements lets you see manioc flour

Start with the Rio Moa, because the river trip is how you reach everything else and it shows you the forest at its best.

🌤️ When to go?Weather, crowds, and seasonal trade-offs

  • Dry Season (June to September): Rivers drop, trails firm up and rain is lighter. Days reach 30 to 34°C (86 to 93°F), nights dip to 18 to 22°C (64 to 72°F). Cold snaps called friagem can cool nights further.
  • Wet Season (December to April): Heavy downpours, 24 to 32°C (75 to 90°F), flooded paths and muddy roads. Boats run easily, overland access is hard.
  • Shoulder (May, October, November): Variable rain, fewer visitors.
Daylight stays near 12 hours all year, and visitor numbers are tiny in every season. Book river transport early for July and August.

🛏️ Where to stay?Where staying makes the most sense

No lodging exists inside Serra do Divisor National Park, so you sleep in Cruzeiro do Sul, the nearest real town, or in Mâncio Lima, about 40 minutes away by road. Cruzeiro do Sul has simple hotels and guesthouses at roughly US$20 to 50 a night, plus restaurants and the airport. Mâncio Lima is quieter, with a few basic pousadas at US$15 to 30, and it is the usual gateway for park trips. The Pé da Serra community, about eight hours by boat on the Japiim and Moa rivers, has three small pousadas near the main sights. Hammocks are common on boats and in riverside houses, so bring your own.

Expect to spend about US$55 to 100 a day around Serra do Divisor National Park, with guides and boats taking the biggest share. The park charges no entrance fee, but trips are organized through local operators.

🥾 TrailsWhere to hike in Serra do Divisor: trails for every level

Serra do Divisor National Park is more about river and forest excursions than waymarked hiking, and named, measured trails are not the norm. Most visits combine boat travel with guided walks.
  • Forest walks from river landings: Short guided hikes of one to three hours go through dense, humid forest with roots, mud and creek crossings. Difficulty is easy to moderate, mostly from the heat and slippery ground.
  • Ridge approaches: Longer expeditions toward the Serra do Divisor ridges take several days with camping, and are strenuous and remote. They need an experienced guide.
  • Wildlife: Expect monkeys, many

  • Wildlife: Expect monkeys, many birds, caimans along the water and rare species deeper in the forest.
Public transport stops at Cruzeiro do Sul, where you arrange boats and guides locally to reach the park. Crowds are essentially absent. Check with ICMBio in Cruzeiro do Sul about permission and entry rules, since access is managed and you should not enter without arranging a guide.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetyStaying Safe: What Travelers Should Know

Serra do Divisor is remote, wet and roadless, so preparation matters more than danger. Trails are muddy and slippery, navigation is poor, and you need a local guide, which the park practically requires. Rivers rise fast after rain. Expect mosquitoes, so carry repellent, long sleeves and malaria precautions. Snakes and insects are the main wildlife concerns; watch your footing and wear boots. Bring water treatment, a dry bag and extra food, since help and phone signal are far away.

Plan on 3 to 5 days for Serra do Divisor National Park, since reaching it takes a full day. Cruzeiro do Sul is the base, and Mâncio Lima is about 40 minutes away. River trips toward the Môa River and Serra do Divisor trails take 1 to 2 days each way depending on water levels.

We 💚 feedbackFinal thoughts on exploring Serra do Divisor

Serra do Divisor National Park works best as the wild finale of an Acre or Peru Amazon route, after Rio Branco or Cruzeiro do Sul. I would hire a local boatman in advance and carry a water filter and plenty of insect repellent.

✈️ When did I visit Brazil?
Call it good timing or luck, but I was able to celebrate Carnaval in Rio de Janeiro in February 2022, after a round trip in the north and east coast.
