The Marriot house reef is a great place if you're staying at the hotel. The dive shop is right at the entry and the people there are all awesome. You can snorkel along the wave break going west then turn and come back along the reef. Lots of lion fish, a moray ell and sea horse at the end of the reef. At the bottom 90+ feet, there are some WW2 airplane pieces from a ship wreck. Dove the house reef several times while in Curacao. The best place to stay on the island.
