Lençóis Maranhenses National Park, a UNESCO World Heritage site in Brazil, is a stunning natural wonder featuring vast, undulating sand dunes interspersed with crystal-clear freshwater lagoons that form during the rainy season. This unique coastal desert landscape, sculpted by wind and water, supports a surprising array of wildlife, including migratory birds and fish that thrive in the seasonal pools. Visitors can explore this breathtaking expanse through guided tours, marveling at the surreal beauty of white sands stretching toward the horizon, contrasting with vibrant blue and green waters.
