Imagine a desert with thousands of crystalline lakes formed by rainwater. This place exists, in Maranhão. Maybe you have seen it on TV, but nothing overcomes the sensation of being their firsthand. Besides, the Lençois, the city of Barreirinhas offers excursions on the Rio Preguiças, by boat, floats and radical excursions on 4-wheelers. You will not only be in contact with nature, you will be part of it.
