Those cool fall temps are beginning to dip a little lower each week, so it’s a pretty solid time to plan one last weekend escape to the islands. But it’s an even better time to win a trip there, thanks to the St. Lucia Tourist Board’s Six Nights in Paradise sweepstakes, now live on Facebook. Through Friday, you can enter to win a six-night, seven-day grand prize vacation package for two, valued at over $10,000 and featuring two the island’s most exclusive resorts.

Cap Maison

Situated along a jaw-dropping, oceanfront bluff in Gros Ilet, this 49-room luxury resort occupies an elegant, Spanish Caribbean-style estate and boasts a range of fine appointments and amenities. Dine in the top-rated Cliff at Cap Restaurant, ranked among the best culinary venues in the Caribbean; then enjoy a private, sunset toast on the resort’s private dock, where a champagne zip-line will keep you popping bottles of bubbly into the night without interruption.

Ladera Resort

St. Lucia’s iconic Pitons are one of the Caribbean’s most spectacular sights, and there’s arguably no better place to admire them than from the grounds of this 23-suite luxury resort (pictured), perched high atop the hills of Soufrière. Each of the “open wall” suites unfolds toward the Pitons and the Caribbean sea, with unobstructed views that still ensure complete privacy from adjoining rooms. If you can tear yourself away from your suite, head to the acclaimed Dasheene for an unforgettable dinner al fresco.
