With low-season savings and balmy high-season temps, October and November are arguably the best times of the year to take a Caribbean island vacation. While not squarely in the Caribbean, this week’s pick for a weekend escape zeroes in on the Out Islands of the Bahamas, a sleepy archipelago located just east of Florida’s Atlantic coast and to the northwest of the swanky Turks and Caicos islands.

World-renowned for the cerulean seas and shallow bonefishing flats that surround the area’s islands and cays, the Out Islands are a favorite vacation spot of beach lovers, snorkelers, and fishermen alike. And when it comes to sailing and boating, it’s tough to beat the Exuma chain, boasting some of the most picturesque waters in the world.

On Great Exuma, the hub of activity in these parts, the luxury Grand Isle Resort & Spa offers a collection of 1- to 4-bedroom estate home accommodations, ranging from 1,250 square feet to over 5,000, and fringing one of the loveliest stretches of shoreline on the island—Emerald Bay. The AAA four-diamond property boasts a full-service resort and spa, and has been named as one of TripAdvisor’s top 10 luxury resorts in the Caribbean.
