The current can pick up with little warning around the wall section, so plan your dive to work into the current on the outward leg and ride it back. Confirm conditions with your boat charter operator before entering, as surge inside the cave is current-dependent.
Entry into the water can be treacherous if waves are surging into the Bight. Ask a member of staff before attempting to swim or snorkel in the Bight.
