It’s easy to imagine that you and that special someone are alone on a deserted tropical island from many vantage points on this bucolic beach. On the western side, sit by a shallow shelf and watch small tidal pools empty and fill with the ebb and flow of the sea. From here, there’s nothing to see but uninhabited Thatch Cay offshore and St. John and the British Virgin Islands beyond. Swim off the center and eastern shores where the ocean floor is soft sand. There’s a lifeguard, restrooms, and wood tables. Pack a romantic picnic to share under the palms. Find fixings in nearby Red Hook. Entrance is $5 per person and children 12 and younger are free. There’s also a $2 parking charge.
