We'd been to St.Barts before but this was our best trip. Stayed in a gorgeous hillside villa: Flamands Blue, www.stbartsvilla.com, where we'd wake up in the morning and look over the ocean, and have coffee and fresh goods from the bakery.
We snorkeled all the best places but found Marigot, Colombier, and Petie Anse to be the best. This island is ROMANTIC with pristine, uncrowded beaches. It's France, with the wine and ambiance, and sexiness too.
Can not wait to return!
