Took a taxi over to Maho Beach and spent the day at Sunset Beach Bar, which was incredible. It's right next to the airport with beach access. Nothing beats watching a plane come in right over your head as you swim in crystal clear water!
Rented a golf cart and went to the national park in Grand Turk. Beautiful place with nice sand and good snorkeling. We decided to try going there because we could get away from the crowds and we're so happy we did.
