In June 2011, the park expanded with the opening of The Grand Reef. This reef was needed due to the original reef having a persistent salt water leak, which affected the ground water, and replaced the original reef with Freshwater Oasis. The Grand Reef features a white-sand beach, palm-lined island and underwater grottos filled with moray eels, reef sharks and scores of other tropical fish. Activities range from snorkeling with eagle rays to crossing a rope bridge over a shark-filled lagoon.
