Strictly speaking, Lencois Maranhenses is not an actual desert, however when you are there, walking among the smooth white dunes without any vegetation, you can't help it but feel like you are in some place like Sahara. Only the color of sand is a bit different. What is really strange is that this National Park is located in the tropical rain forest climate, surrounded by the sea from one side and by lush green woodlands from the other. Nevertheless, it's not this fact that attracts thousands of tourists to visit Lencois Maranhenses from Brazil and all over the world. During the rainy season, starting from February, the gaps between the dunes become filled with rainwater creating unusual, spotty landscape, especially amazing seen from an airplane.
