You have two choices for how to access the beach at Isaac Bay: Either hike from Jack's Bay or arrive by boat. The hike is worth the extra effort. The breathtaking beach is home to nests of hawksbill and green turtles. (Keep your distance, though; the nurseries are protected by the Nature Conservatory.) The calm and deep waters of secluded Isaac Bay make it great for swimming and even better for snorkeling.
