On the Atlantic coast in Northern Brazil in the state of Maranhao there is a big white desert-looking landscape. It is called Lençóis Maranhenses - "The linen of Maranhao". The park consists of large dunes of incredibly white sand, sometimes they are quite steep. It is widely famous as the white desert of Brazil, and indeed the landscape looks almost like a desert. Almost. All around the place there are those long lagoons of fresh water. Because the desert is surrounded by equatorial rainforests there is a lot of rainfall. So the water from the rain gathers into the lower places and produces this unique landscape.
Since 1981 the whole desert is made into a national park. Access for tourists is permitted so although the park is very remote from all bigger population centers there are still ways to get there.
