The most interesting area to go scuba diving is probably at the northern part of the Rock. On the rocky sea bed that goes down as far as 15-17 metres, you will see two huge rocks, leaning one against the other, that create a narrow passage with the "roof" covered in parazoan.
Before swimming further down to a depth of 27 metres, you can see ahead large dentexes, and, if you are really lucky, some cute sunfish, or maybe even a shoal of barracuda. Swimming down along the wall, amidst yellow gorgonias and spirogyraphs, you will also be able to admire several species of colourful nudibranches and maybe even some eagle rays.
Be careful here, however, because the current can be quite strong sometimes.
Only if you go further down to a depth of 40-45 metres will you be able to see the beautiful marine flora consisting of fans of red gorgonias , and in the many gorges, amidst tiny branches of coral, dozens of lobster feelers will appear by magic; in the larger cracks and gorges usually some shy groupers and various shoals of sargos and corvinas like to hide.
If you want to go back to your boat just head in the opposite direction until the water gets shallower; here you will no doubt come across redfish, conger eels, moray eels and even the odd, very impressive spider crab. At this point your scuba diving tour is back where you started: the shallow water that is almost always crystal clear will be pure joy to all underwater photographers.
