Sancho Bay, Fernando de Noronha, Brazil

The island of Fernando de Noronha is a protected marine ecological reserve, and only 420 tourists are allowed to access the beach at one time. Those who do visit will find 15 beaches with sparkling blue water and white sand beaches — but Sancho Bay, surrounded by natural walls, is one of the most unspoiled and secluded spots on the island. It is accessible only by a ladder that’s wedged in a rock crevice.
