South of Morro De Sao Paulo sits the island of Boipeba. The village of Boipeba is quiet, rustic and said to be what Morro De Sao Paulo was 20 years ago. The island's coastline is pristine, with more than 20km of beautiful, deserted beaches, including Ponta de Castelhanos, known for its diving. Restaurants serving great seafood line the beach where the river meets the sea.
