These islands are at the western entrance to St Paul's Bay and the only way of reaching the islands is by boat.  There are various dive sites at St Paul's Islands, including the location where St Paul was supposed to have been shipwrecked.  Although there is nothing to show this, there are other remains such as some plates and ribs form an old destroyer and a small ferry sunk purposely in 1984.   Another dive, is an open water reef dive.  The seabed is covered in rocks and boulders, and small sea urchins and fireworms can be seen.  Another dive is St Paul's valley, found between the two islands.  The seabed is of white sand and is covered in boulders and Posidonia, where numerous wrasse can be found.  Between the seagrass, broad-snouted pipefish can also be seen.
