Resort guests should stop by the Towel Depot prior to departure to pick up towels for the day. Because the island is part of the eco-preserve, guests should also bring drinks and snacks with them. There is no restaurant on the island. Expert Tip: reserve your seats on the boat 24-hours in advance to avoid delays. Visit All Water Excursions' website to book.
