The Parque Nacional dos Lençóis is an ecological paradise with 155,000 hectares of dunes, rivers, lakes and wetlands. A singular ecological phenomenon, its has been formed during thousands of years of wind movement. The landscape is astonishing wonderful: a white sandy carpet without end in sight, as if you were on a desert. Unlike a desert however, there is plenty of rain and rivers in the region. It is the rain that actually creates the Lencois and its landscape. The rain fills the uncountable lakes and the magnificent landscape. Some of the most famous lakes are the Lagoa Azul and the Lagoa Bonita for their beauty and excellent swimming conditions.
