The archipelago of Fernando de Noronha is a UNESCO World Heritage Site with a delicate ecosystem. Visitors are restricted, but the lucky few are rewarded with unrivaled beaches and soothing warm waters filled with dolphins and sea turtles, making Noronha one of the world’s top diving destinations. On land, hike the ecological trails of Jardim Elizabeth, the Esmerelda Coast or Sancho Bay, which culminates in a climb up a steep set of stairs carved into the split of a cliff.
