A popular bareboat anchorage, Butterfly Bay is situated on the northern side of Hook Island. There are limited public moorings and snorkelling can be enjoyed along the bay edge or just off the beach. Offering coral outcrops with shallow walls, the bay is populated by many small, colourful reef fish species. The best of the bommies is found in the centre of the bay, although it may be difficult to locate at high tide. Be wary of tidal currents when moving towards the centre of the bay, away from the edges.
Visibility: 2 - 10 metres. Diving depth: 5 - 12 metres. Bottom: coral cover with large patches of coral rubble and silty sand.
