Visit Sao Luís & Lençóis Maranhenses National Park, Brazil
São Luís' historic centre is rather how the historic centre of Salvador looked before the government investment that has made it as shiny as it is today. Lençóis Maranhenses National Park is located in the state of Maranhão and is famous for its incredible 40 metre sand dunes, stretching 50km inland from the coast, and 70km along it.
