From Barreirinhas: 3-Day Trekking Tour to Santo Amaro

Traveling through Brazil’s Northeast often conjures images of lively samba rhythms and sun-drenched beaches, but for a truly unique adventure, a journey into the Lençóis Maranhenses National Park offers something unlike any other. This 3-day trekking tour, starting from Barreirinhas, takes you deep into the largest humid desert in the world, where dunes meet lagoons in a landscape that’s both surreal and stunning.
For $679 per person, you’ll spend three days hiking through vast sands, crossing rivers by boat, and staying overnight in remote villages. What we love most? The chance to witness sunset over lagoons that seem to glow with warm colors, and the experience of walking through an almost otherworldly landscape. But be prepared for early mornings and uneven terrain — this isn’t a casual stroll. It’s best suited for those with a moderate fitness level who crave authentic, off-the-beaten-path adventures.
One potential drawback? The itinerary’s reliance on weather conditions—heavy rains or strong winds can shift plans.

If you’re looking for a balanced mix of adventure, scenery, and local culture, this tour is an excellent fit. It suits travelers eager to walk, explore lagoons, and stay in small villages, rather than those seeking luxury or a relaxed beach vibe.

A highlight is the visit to the Farol Lençóis, where climbing 160 steps rewards you with panoramic views of the sea, the river, and the dunes—a perfect spot for photos and a moment of awe. The contrast of the beach of Caburé, with its narrow sand peninsula between water bodies on either side, is striking and offers a break for lunch (note: lunch is not included).
After lunch in Atins, you switch to a 4×4 vehicle for a short ride to the trek start. The first walk of about 8 kilometers takes you to Baixa Grande, where you’ll spend the night. The landscape here is an expansive sea of sand dunes and lagoons, a scene that feels almost surreal—like walking through a living painting.

Early mornings are part of the rhythm here, with a 13-kilometer walk from Baixa Grande to Queimada dos Britos. Along the route, you’ll encounter various lagoons, each with its own character and color, making every step visual feast. The walk is physically demanding but varied, with plenty of opportunities to stop, take photos, and soak in the scenery.
