Backpacking in Serra do Mar State Park
🌟 Highlightnational park ranked #14
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

Serra do Mar State Park is best known for Atlantic Forest that climbs steep escarpments right behind Brazil’s coast, in São Paulo state, inland from Santos and the Baixada Santista. The trails are muddy, the forest is thick with bromeliads, and monkeys and toucans turn up. Skip the roadside viewpoints, which are crowded and short. Book ahead for guided nuclei, since walk-ups are turned away and a wasted bus ride stings. I paid US$2 for a pastel and sugarcane juice at a stall near Cubatão, and it fueled the climb. Unlike Ilhabela, this park is wet, steep and quiet.

✨ Why go?
Ranked #14 national park in Brazil
What makes this national park worth exploring

Serra do Mar State Park suits backpackers who want Atlantic Forest without the Rio crowds. The park is huge, so you choose between the humid, mossy slopes above Cubatão and the quieter coastal sections that run toward Picinguaba. Independent travelers can link forest walks with beach villages, and sleeping options range from simple campsites to pousadas in nearby towns. Some historic routes need a permit or a local guide, which suits self-guided types who plan ahead. Expect steep, muddy ground, dense canopy and birdsong rather than big open vistas. It rewards people who like effort and are happy to leave the postcard views to other parks.

💡 HighlightsMust-see experiences and standout moments

  1. Caminho do Mar: the old cobbled colonial road linking the plateau to the coast, shaded by dense forest and dotted with stone ruins.
  2. Rancho da Maioridade: a rest stop along the old road with historic ruins and a sense of Brazil’s imperial past.
  3. Cruzeiro Quinhentista: a 1922 Independence-centenary monument at the start of the old road in Cubatão, one of several along the route.
  4. Núcleo Picinguaba: the coastal section where forest meets the sea, with quiet beaches and short trails.
  5. Trilha do Corisco: an old colonial path climbing the ridge between the Picinguaba side and Paraty, overgrown in places and only for experienced hikers with a guide.
  6. Praia da Fazenda: a beach at the foot of the forested slope, with a river meeting the sea.

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

  • Cool dry months (May to September): Trails are firmest and views from the ridges are clearest. Days run about 12 to 24°C (54 to 75°F), with chilly mornings in the highlands. Weekends are busier and school holidays in July bring the most visitors.
  • Hot wet months (December to March): Expect 20 to 30°C (68 to 86°F), afternoon downpours, slick roots and heavy mud. Daylight stretches longest, but fog often closes the view. Lodging near Santos climbs around New Year and Carnival.
  • Shoulder months (April, October, November): Moderate temperatures, thinner crowds and lower prices make these the easiest months to plan.
Start hikes early, because afternoon cloud and rain build quickly on the escarpment.

🛏️ Where to stay?Where staying makes the most sense

The easiest bases are the towns just outside the park, since overnight options inside are limited. Cubatão sits at the foot of the Itutinga-Pilões section and has simple, cheap guesthouses at roughly US$15 to 30 a night. Santos, about 30 minutes from Cubatão by bus, has the widest choice of hostels (dorms from about US$12 to 20) plus plenty of cheap restaurants. For the southern Curucutu section, Itanhaém and Peruíbe on the coast offer pousadas at US$20 to 45, and the Marsilac area on the São Paulo side has a few rural lodgings.

Expect howler monkeys, toucans, tanagers and many butterflies, though sightings depend on the quiet. Terrain is humid and slippery, so wear boots with grip. Some sections need advance booking or a guide, and entry rules vary by núcleo, with modest fees at some and free access at others. Weekends fill up on the popular routes, while weekdays are calmer. Public transport reaches the nearest towns, but the trailheads often need a short taxi or local bus ride.
⚠️ 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.

🛡️ SafetySafety Tips and Common Scams in Serra do Mar State Park

Serra do Mar State Park is mostly straightforward, but the weather is the main variable. Mist and sudden rain turn steep, rooty trails slippery, so wear shoes with real tread and carry a rain shell even on sunny mornings. Some paths are poorly signed, so download an offline map and stay on marked routes. Insects, ticks and the occasional snake are normal in the Atlantic Forest: wear long trousers, use repellent and watch where you put your hands. Wildlife such as monkeys should never be fed. Bring more water than you think you need, tell your lodging your route, and turn back early if cloud drops.

FAQCommon questions from travelers

Plan two to three days for Serra do Mar State Park if you want to hike one or two sections properly. The Itutinga-Pilões trails near Cubatão fit a single full day, while the Curucutu area on the southern side deserves a second day. Longer treks across the escarpment between nuclei can take three days or more.
Yes, you can reach Serra do Mar State Park by public transport, though some sections need a final transfer. Buses run from São Paulo to Santos (about 1 hour), and local buses connect Santos to Cubatão in roughly 30 minutes. Remote nuclei like Curucutu are easier with a taxi, a rideshare or a guided transfer from Itanhaém or Marsilac.
Entry to most areas of Serra do Mar State Park is free, though some trails and nuclei require advance registration or a guided booking through the state park system. Costs are typically US$0 for standard day visits. Camping and organized activities may carry small fees, often under US$10, so check the official site before heading out.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackParting advice and final tips

Many first-timers overlook that Serra do Mar State Park is really several separate sections, each with its own rules and character. I would pick one núcleo, confirm access rules and book ahead, then pack rain gear and spend the extra day lingering in the coastal forest.

✈️ 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.
