Beautiful beaches ... a lot cheaper to take your own taxi that use the cruise ship excursions. Be sure to give yourself lots of time to get back to the ship because traffic going back into town does get busy at the end of the day.
My favourite island in the Caribbean. We rental a jeep for the day and explored lots of beaches. The highlight was the Lolo's in Grand Case. It's an excellent open air BBQ... great food and great value.
