Imagine stepping from a jangling Toyota 4x4 onto warm sand as the wind sculpts the dunes ahead. The climb up a wooden stair feels abrupt after the ride — then the landscape opens: white and gold ridges punctuated by brilliant blue lagoons that collect the rainy season's bounty. You walk between bowls of water and sand, pausing to swim in clarity that seems impossible inland.

History
The dunes formed from coastal sands shifted by wind and stabilized temporarily between river plains; local communities in Barreirinhas developed livelihoods around river transport and guiding.
Conservation
The lagoons are sensitive to pollutants and foot traffic; follow guides, avoid soaps in the water, and pack out all trash to protect this seasonal ecosystem.

Time your visit for late afternoon
Aim to arrive at the viewpoint an hour before sunset for the best light and cooler sand for the return hike.
Bring a reusable water bottle
Carry at least 1–2 liters per person — sand hiking and sun exposure increase hydration needs quickly.
Wear sand-friendly footwear
Light hiking shoes or sturdy sandals with closed toes handle hot, loose sand and short climbs better than flip-flops.
Protect the lagoons
Avoid sunscreens and insect repellents before swimming and follow the guide’s path to minimize impact on fragile ecosystems.
Closed-toe sandals or lightweight hiking shoes
Better grip and protection on hot, shifting sand and short dune scrambles.
Sun protection (hat, SPF 50+ sunscreen, sunglasses)
The open dunes offer no shade; strong UV and reflected light from sand increase exposure.
summer
1–2 L reusable water bottle or hydration pack
Hydration is critical during sand hiking and in late-afternoon heat.
Swimwear and quick-dry towel
Many lagoons invite a refreshing swim — pack a towel and dry clothes for the return.
