Meet the guide at your hotel in the morning. Then, relax on a jeep drive from Barreirinhas to the Lencois Maranhenses National Park, known for its vast sand dunes and desert landscapes. Arrive at the park and start walking from a lagoon. Walk across the sand to another lagoon.

Stop at a local restaurant in the middle of an oasis to enjoy a delicious lunch. After eating, head outside to watch the beautiful sunset over the dunes. Admire the colorful sky as the sun goes down. Finally, get back into the jeep and drive back to your hotel in Barreirinhas to finish the activity.
