For a nice day trip, catch the ferry to the laid-back island of Itaparica.Salvador is also the gateway to many other nearby attractions such as:
Praia do Forte. Beach town with the "Project Tamar" turtle sanctuary.
Imbassai. Just a few kilometers further North from Praia do Forte, this relaxed village's beach lies between the sea and a river that runs parallel to the ocean for a few hundred meters. Unique panorama.
Boipeba. A beautiful and very pleasant island.
Morro de Sao Paulo. Very frequented island by tourists and locals, plenty of restaurants, hostels and bars. It has four beaches with translucent water.
Massarandupió. Just 90 km from Salvador, it's a true paradise, a semi-desert beach, with a small river. Walking by the beach you can reach a naturist area.
