More ways to explore the area's outdoor wonders
You roll out at 8:30 AM in a Toyota 4x4 and the dunes open like a silent road, sand sighing under the tires as the vehicle climbs toward the first lagoons. Lagoa do Gavião appears first: water bright against pale sand, daring you to swim. The route alternates between mangrove channels and open Atlantic views; wind tugs at your hat as you crest each dune.

Bring cash for meals and small purchases
