Here’s a round up of the sites we dived on our trip to Durban in June 2013, and on prior trips up north:
Durban diving involves a surf launch from the beach near the harbour entrance, and a characteristically long boat ride, usually of at least 25 minutes. It’s essential to carry an SMB. We dived with Calypso and highly recommend them.
There are some nice Durban dive site summaries here, here and here.
