Lencois Maranhenses National Park, Barreirinhas

(4.8/5 based on 3,600+ reviews on the web)
On the banks of the Preguiças River, Lencois Maranhenses National Park is quite extensive with 1500 square km (930 sq mi) filled with dunes up to 40 feet tall and freshwater ponds called lagoons--whose waters range from bright green to azure blue. Composed of large, white, sweeping dunes, at first glance Lençóis Maranhenses looks like an archetypal desert. In fact, it outside the Amazon Basin, a region subject to regular rainfall. This causes a peculiar phenomenon: fresh water collects in the valleys between sand dunes, dotting the desert and landscape with blue and green lagoons.

Rare geological phenomenon formed the most famous lagoon called Lagoa Azul (Blue Lagoon), which is closer and more crowded. Lagoa Bonita (Beauty Lagoon) is further out, less traveled, and famous for its charm and excellent swimming conditions. Since personal vehicles are not permitted into the National Park, you can hire a guide service to take you to the dunes and lagoons with a 4 x 4 Jeep. You can rent a dune buggy, but beware that buggy's are prone to getting stuck in some sands, can run out of fuel, and are not permitted in all places. You can also opt to walk out to the dunes and lagoons, as well as hire a trekking service to escort you across these strange lands.

  • Unique landscapes in a special setting. Those who visit the lençóis maranhenses never really forget that incredible luminosity that rebate in the sand from the Sun, the invigorating baths in the middle of deserts of sand and simplicity of the people. Amazing:)

  • The National Park, with its dunes and lagoons is exemplary only. Hosted in St. Louis hired an agency that did the back. The van leaves at 4:30 in the morning and the trip to Barreirinhas takes 4 to 5 hours. Getting there is need to take the special vans and transport takes 1 hour to the dunes. Arriving in the dunes you need to walk 20 to 30 min until the ponds, depending on the time of year.
