Cais do Porto is your starting point to explore Paraty Bay. Saveiros are the larger boats, and you can go on a tour with other travelers. These boats usually leave in the morning, and you stop at beaches and near islands. Some of these islands are private, with posh mansions and yachts.

If you are with a small group you can alternatively rent a smaller fishermen's motor boat, and arrange for a private tour. There are several diving and snorkeling spots in the area, and you can have more control on how long you stay where. Make your arrangements directly at the pier, or through one of the local travel agencies.

The sea of Paraty bay is very gentle, and you shouldn't get seasick. Even if you are not an athlete, the water is so clear it will be hard to resist going for a dip. If you don't swim at all, ask for a stop at a favorite beach such as Praia da Lula. With a raft you can be dropped right on the sand, without even getting your feet wet!
