camping
No restrictions so far, but there is some talking, due to garbage left behind. Do your part!
lodging
Most people sleep in Barreirinhas and do daytrips. However, the dunes are far more accessible if you stay in Atins, or even better in Canto de Atins. Mandacaru and Caburé are less convenient alternatives. Paulino Neves offers proximity to similar sights Pequenos Lençóis, although not inside the actual national park. There is also the little explored town of Santo Amaro on the park´s western rim.
