Tides: Tide tables It is best to dive at high slack water to get some depth going around the Island
Depth: The maximum depth is about 12 metres.
Site entry/exit: Enter the water from the beach and stay on the right-hand side of the bay and head out to the island. The left side of the bay usually has moored boats and lines to the shore.
Underwater directions: Follow the rocks out and around the point, there are gullies, swim-throughs and walls rich with anemones, soft corals and sponges, along with large wrasse, crabs and the odd lobster. There is also a 'blow hole' that can be entered under water. A light is needed for this, and it shouldn't be attempted if there is a large swell. Around the back of the island in about 8 metres there is a large cave entrance that can't be seen above water. Enter the cave and swim in for about 8 metres, and surface inside the blow hole!
Site Hazards: Boats and swell, Sometimes boats come through the gap between the Island and the shore at high tide.
