Chiclana de la Frontera has a lot to offer, even underneath the water level. The Costa de la Luz is an ideal place to base yourself for a scuba diving holiday or even obtaining your first qualifications. The little known Trafalgar area from Roche to Sancti Petri is riddled with ships cannon, cannon-balls, and anchors left from that famous sea battle.
Although visibility is not always fantastic (average 5-8m), the sea temperature in this part of the Atlantic Ocean is often very good, with plenty of things to see, especially at the locations closer to the coast like at Rogers Reef in Chiclana, from 16 degrees in the winter up to 30 centigrade in the summer. In the cooler water of the Tarifa Coast there is normally better visibility of 20 + meters. There are, of course, days with heavy seas but these are rare and there are plenty of dive sites or other activities to choose from so you should always find something to do.
But be careful: The current can be strong, so you should be an advanced diver or in company of some locals who know the spots or just book your open water dive experience with Costa Diving. This diving centre in Chiclana de la Frontera offers their services and shows you the nicest places.

The Top 6 Dive Costa de la Luz Dive Sites

1. Rogers Reef, also known as the northern end of "Reteletis", which is a very large reef several miles long. This is an easy dive with lots of sea life often visited by many different kinds of fish. It is only 2 km from the castle of Hercules. The reef is in the form of a long step or shelf. The most upper part is at approximately 7 meters and the lower part is at 12 meters. This is also a very good place to use Nitrox. You can see there large shoals of barracuda or a stingray the size of a small car. There is also a Roman anchor and a Phoenician amphora which is over 2000 years old.

2. Pepi's Rock - This is a lone standing rock between Rogers Reef and the port of Sancti Petri. It is covered with a local soft coral called locally "gorgonians" giving it a bright orange colour. This rock is often home to fish like large groupers, sea bass, and swarms of damsel fish. Max depth 18 meters. The top of the rock is at about 7 meters.

3. La Piedra que Revienta (also known as the Cannons)- This is an undersea rock formation between Trafalgar and Cadiz. Because of its depth of 4 meters at the surface and location, about 3 km off shore in a busy shipping lane, it has been the final resting place of many a ship wreck. Max depth around 25 meters. There are at least 60 massive cannon, large anchors, cannon balls etc. This place is Unbelievable!

4. La Luna (also known as part of Reteletis) - About 4 km from the castle of Hercules this is a large crater in the shape of a half moon, blasted into the reef by a naval missile. Reach in sea life living in and around this strange hole is varied and often covered in brightly coloured invertebrates and brittle stars. Max depth is 14 meters.

5. Los Navios - a rocky reef situated off the coast of Roche, close to the Trafalgar bank. This is a dive that must be timed to coincide with the tides, as currents can be very strong. It is deep up to 25 meters. This is a good place to see large Tuna buzz past in shoals. This place is often visited by "very large fish" of different species including sword fish and corvine.

6. Los Marrajos (the meaning in local Spanish is "the sharks") - Depth 8 to 16 meters; this area is loaded with rock formations, sunken ships, small caves, marine life and the possibility of bumping into the odd dogfish or blue shark, although this is quite rare these days.
