A Deep Dive into the Experience

Starting Point and Logistics
The tour begins at Av. Beira Rio, 83 – Centro, Barreirinhas, a central spot easily accessible for most travelers staying in the town. From there, your journey into the sand dunes starts, often with a quick boat ride through the Rio Preguiças, which itself is an attraction with sights like mangroves, riverbanks, and sandbanks. This boat segment is not just transportation; it’s part of the scenic experience that sets the tone for the day.
The activity lasts around 5 hours, with the option to start early morning or late afternoon—perfect if you want to catch the sunset. The tour is private, so your group enjoys personalized attention, and you won’t be sharing the experience with a large crowd. This intimacy allows guides, like Thais or others, to tailor the route based on your fitness and interests.
The Fatbike Itself and the Dunes
When it comes to the fatbike, think of a sturdy, wide-tired bike designed for soft, sandy terrain. We loved the way riding over the dunes gave us a feeling of gliding rather than trudging, thanks to the bike’s design. However, the terrain can be physically demanding—if you’re not used to cycling on loose sand, it might be a workout.
Because there are no designated trails, the route is flexible. Whether you want to pedal slowly, taking in the scenery, or push a little harder, the guide will accommodate your pace. For novice cyclists, the activity remains accessible, but it’s good to be aware that sand biking requires some effort and balance.
Exploring the Region
The Pequenos Lençóis Maranhenses conservation unit is a quiet, pristine area. Our guides emphasized the flora and fauna, with bird flocks sometimes visible overhead—ideal for nature lovers. The dunes here are smaller than the famous large-scale Lençóis, making the experience more intimate and less crowded.
Throughout the day, you’ll make stops for swimming in lagoons, rivers, and the sea, which is a highlight for many. No cutlery is needed during the barbecued fish sticks on the sand, a casual and tasty treat that adds to the adventure’s authenticity. Fresh coconut water quenches your thirst amidst the desert-like dunes.
The Boat Ride and Natural Attractions
Returning to the boat for the scenic ride back is a highlight. Expect to see mangroves, Igarapé (small waterways), coastal scrubland, and sandbanks. The boat ride offers stunning views and a chance to spot local bird species, adding a layer of wildlife appreciation to your experience.
According to reviews, the boat trip through the mangroves is “a great natural experience,” with one traveler noting it was “a beautiful boat ride through the mangrove landscape and riverbed.” The natural scenery combined with the sandy dunes at sunset creates unforgettable photographs and memories.
