Var & Alpes-de-Haute-Provence, France
It turns out a 15-minute boat ride is enough to keep most tourists away. That’s all it takes to get from Cannes to Saint Marguerite, the largest of the largely unspoilt Lérins Islands. When you arrive, get your geek on at the fort museum, which contains the cell of the 'The Man in the Iron Mask' and is therefore probably the closest you’ll ever get to Leonardo di Caprio. The smaller, less touristy, and in some ways more charming of the two islands is Saint Honorat, which has been home to a community of monks for over 1,500 years. Lérins Abbey and the 15th-century fortified monastery are open to visitors, and you can buy homemade wine and honey for all the folks waiting for gifts back home.
