Two islands in the bay that are definitely worth visiting. The smaller is St Honorat, which has a monastery and ruined castle. The monks sell monastery-made food/drink products like wine which make unique souvenirs. The larger island is Ste Marguerite which also has a castle, shops, bars, and restaurants. Find a quiet cove, some shade from palm trees, and a cheap snorkel before you swim around the rocky coves. A return ticket to Ste Marguerite is €11 with ferries departing every hour roughly from 7 in the morning until about 5:30 at night - ask for a timetable. The ticket to St Honorat costs €13, and visiting the fortified monastery costs €3/pax. The timetable and information is also available in a brochure kept in most hotel lobbies.
