Dive Sites in Guernsey

Guernsey waters are home to incredible dive sites that cater to a diverse range of abilities. There are fascinating shore dives perfect for beginners and breathtaking reef dives offering more of a challenge. Although there is a seemingly endless list of places to discover in Guernsey waters, the best scuba diving in Guernsey can be found at these dive sites.

Havelet Bay

This shore diving spot is perfect for beginners, nestled in a sheltered bay and protected from the winds. Conditions are consistently calm, making it a safe place for newbies to explore underwater. The variety of marine life is very impressive in this bay and divers will regularly encounter spider crabs, flatfish and lumpsuckers. If you are short on time or not a confident diver, you can also snorkel in Havelet Bay and still discover the underwater world. Overlooked by Castle Cornet, this spot also offers great scenery above the water too.

Saint’s Bay

While Guernsey’s tidal range is renowned for being dramatic at times, Saint’s Bay is another section of the island’s coastline that remains safe for diving and snorkelling. Another shore dive site that is great for beginners, Saint’s Bay is bursting with vibrant marine life throughout the summer months. It is a quiet and peaceful spot that is ideal for a relaxing beach day, alongside a dive or snorkel.

Cement Wreck

The most iconic wreck site to be discovered off the coast of Guernsey is Cement Wreck. Captured by the Nazis during World War II, the Dutch ship Oost Vlaanderen was eventually sunk by the RAF and formed the wreck site. Sitting 33m below the surface, the ship has remained relatively intact. It is a safe wreck site to explore and divers will often discover lobsters hiding out within the ship.

DR Rudolph Wahrendorf

Found just outside St Peter Port harbour, the DR Rudolph Wahrendorf is another Guernsey wreck site from the war. The ultimate Guernsey dive site for experienced divers, DR Rudolph Wahrendorf is located at the same depth as Cement Wreck but feels a lot more eerie. Nestled into a muddy seabed and surrounded by murky waters, this wreck site is a true reflection of wartime Guernsey.


On Guernsey’s southern coastline, Peastacks is one of the island’s best reef dive sites. Starting in shallow waters and getting to 35m deep, this site caters to both beginners and experienced divers. It is home to a great number of different species, including conger eels, native to north Atlantic waters. You may also discover the rare species of Ormers, a shellfish that can only be found in the Channel Islands.

Boue Blondel

A few miles from the west coast, Boue Blondel is the reef site with the best visibility. A remote site, many species inhabit this area and you never know what marine life you may discover. This site also has the largest population of seabass in the Channel Islands. Here you will also see beautiful reefs with jewel anemones, fan coral, dead man’s fingers and sunset coral cups.

Les Hanois Lighthouse

Suitable for advanced and NITROX divers only, the dive site at Les Hanois Lighthouse is 30-50 m in depth. With strong currents, it is quite the challenge but that just makes the experience more exciting. You can regularly see lobsters, crabs and conger eels but it has also been known to spot dolphins, whales and sharks in these waters.
