To enter the national park, it is only possible whith tour guides, who are provided by many tour companies at the small town of Barreirinhas. They take tourists in trucks with high suspension wheels, called "jardineiras", which can pass over the sand tracks that leads to the first point where the dunes and the lagoons can be seen. 

Before that, the jardineiras crosses the Preguiças river over ferry-boats. Tourists aren´t allowed to walk alone within the dunes, because its very easy to loose the sense of direction. 

These tours departing from Barreirinhas can be done in just one day, but for more brave and physically prepared people, it is possible to cross the dunes with a guide, and even sleep inside the dunes, which will take, of course, more than one day.
