The experience

The tour starts early from the meeting point in Barreirinhas at 8:20 AM. You'll ride in a shared Toyota 4x4 across an adventurous trail into the dune region. A drive that takes between 25 and 40 minutes depending on conditions. The vehicle handles the terrain. You sit back and watch the landscape shift from town to sand.

Once you reach the dunes, the pace changes. A guide leads you on foot to the lagoons, a walk of 10 to 20 minutes through the region's natural landscape. The lagoons themselves form between the white sand dunes during the rainy season, creating pools of clear water where you can swim. The guide stays with the group for safety and direction, and you have time to cool off in the water before the return journey.

The whole outing wraps by around noon, leaving the rest of your day free. Bring swimwear or a change of clothes, a towel, comfortable shoes, sunscreen and insect repellent. The tour does not include food or drinks, so plan accordingly. If the lagoons are dry at certain times of year, the guide will take you to alternative lagoons with water instead.
