The motor coughs to life at first light and the Rio Preguiças pulls you downstream, low mangrove crowns brushing the hull as the river dares you to look away. In the compact villages along this slow-moving artery of Maranhão, fishermen mend nets, children race along sandy banks, and the water alternates between glass-calm mirrors and channels that hurl you toward the Atlantic.

Wildlife
History
The Rio Preguiças communities developed around fishing and coastal trade; the Lençóis Maranhenses dunes formed from centuries of wind-blown sand interacting with seasonal rains.
Conservation
The region is part of a protected landscape—follow park rules, avoid littering, and do not feed wildlife to minimize human impact.

Waterproof your gear
Use a dry bag for cameras and phones—the spray from the speedboat and river crossings can soak unprotected items.
Bring cash
Small vendors at Mandacaru and Vassouras accept cash for snacks, ice cream, and crafts—card machines may not be available.
Sun protection
Wide-brim hat and SPF 50 sunscreen are essential—the reflected light from water and sand intensifies sun exposure.
Respect wildlife
Do not feed or approach capuchin monkeys; keep a respectful distance to avoid stress or bites.
Waterproof dry bag
Protect electronics and clothing from spray and unexpected splashes.
Insect repellent (DEET or picaridin)
Mosquitoes increase after rains—repellent keeps bites and irritation at bay.
summer
Quick-dry swimwear & towel
You’ll likely swim in lagoons at Vassouras or at Caburé; quick-dry fabrics are practical.
Sun hat and high-SPF sunscreen
Direct sun and reflective sand/water increase UV exposure—protect skin and eyes.
