On the Northern side of Hook Island is one of the best snorkel sites in the Whitsunday Islands, Manta Ray Bay. During winter, as the name suggests, manta rays can be spotted here. All year round you can snorkel with abundant marine life including the Maori wrasse, and you can see a range of hard and soft coral coverage.
Hook Island is home to a number of great snorkel sites that are a favourite with snorkel tours from the islands and Airlie Beach. Other great sites for snorkelling on the fringing reef of this island include Butterfly Bay, Luncheon Bay and the coves around Stonehaven, which is a popular anchorage for charter boats.
