Check in: Wooden walkways meander through the forest where Rockwater Secret Cove Resort's 13 roomy, light-filled, adults-only canvas tent suites―with fluffy king-size duvets and tubs for two―perch above the blue water. Each suite has a deck and views to inspire castaway fantasies. From $315 U.S. through Oct 12.
Explore: At Rockwater's Spa Without Walls, treatments are on a platform at the water's edge with stunning views. Horseback riding, bocce ball, croquet, and beach volleyball, will tempt you to stay on the property, but make time to explore the ocean by kayak. Horseback rides $52 U.S. for 90 minutes;
sea kayaking $57.20 U.S. for half-day.
