The Channel Islands are one of the best places in the British Isles for diving and offer a wide variety of different types of dives. The rugged coastline, shipwrecks, and hundreds of reefs around the different islands offer divers a unique experience that they will find hard to beat anywhere else in the British Isles.

Many divers choose to depart from the south of England on dive charter boats or live-aboard dive vessels.

Many of the different fish and coral, which would be considered rare on the British coast, will be discovered in abundance in the Channel Islands because of their far south location. One of the rare species you may be lucky to discover is ormers. Ormers are a type of shellfish that can only be found on the Channel Islands.

Divers have also reported encounters with massive basking sharks, bottlenose dolphins, triggerfish, and even seahorses. There is a world full of life beneath the surface in the Channel Islands just waiting to be discovered by you!

Most of the diving done in the Channel Islands centers around the islands of Jersey, Sarks, and Guernsey.

Jersey – An Island Made for Divers

Jersey is the largest island in the Channel Islands and lies just ninety miles off the southern coast of England and just fourteen miles from the coast of France. Jersey Island boasts over fifty miles of rugged coastline, sandy beaches, and small isolated and private rocky coves.

When you travel offshore from the main island of Jersey, you’re going to encounter reefs and small islands of all shapes and sizes spread out all over the area. So if you love diving old shipwrecks, then this is one of the best places in the British Isles to do it.

Although diving with full scuba equipment and using spearguns isn’t illegal, it’s a method that is frowned on by the locals of the Channel Islands. The majority of them preferring to spear with snorkeling equipment only. However, if you would rather shoot fish with a camera, not a spear, you’re going to discover diverse and beautiful sea life living just below the surface.

Jersey Island Tides and Currents

There is no denying that the Channel Islands, including Jersey Island, have one of the largest tidal water movements in the world. There can be as much as a 40-foot difference between the low and high watermarks in a big spring tide. Therefore, it’s a great idea to purchase a local dive table and also seek advice from one of the many dive centers before you enter the water.

If you are planning on diving from the shore of any of the Channel Islands, then it’s essential to check out the local tidal conditions. On the other hand, if you’re planning on hitting one of the many dive spots offshore, then you can use the tidal current to your advantage. In addition, there are some fantastic locations available for drift dives around the local islands and reefs.

As an example of the extreme tidal conditions, it’s sometimes possible to walk over two miles from the high watermark out over large areas of exposed reefs and seabeds. At high tide, the island of Jersey has a surface area of just forty-five square miles, but at low tide, that surface area is approximately sixty-three square miles. The tidal conditions around Jersey island are some of the strongest in the world and not something that should be taken lightly even by an experienced scuba diver.

Jersey Island Dive Locations and Attractions

One of the reasons the Channel Islands, including the Jersey Islands, are so popular as a diving destination is the diverse variety of dives that you can do both offshore and offshore. There are dives for all experience levels, including beginner, intermediate, and advanced divers. It doesn’t matter what level of experience you have; the Channel Islands offer something exciting for everyone.

  • Shore Diving Jersey Island – Undeniably, the most popular shore-dive in Jersey Island is Bouley Bay. Bouley Bay offers a large sheltered and rocky cover that lies on the northeast of the coastline. There is a large granite harbor wall and also a rocky promontory called L Islet. As you venture around the bay, you’ll encounter a ring of kelp that eventually gives way to a light, sandy bottom. There is a 10-12 meter gradual slope which makes Bouley Bay perfect for all levels of experience.
  • Bonne Nuit Bay – Bonne Nuit Bay lies to the west of Bouley Bay, and Rozel lies to the east. All three have a similar type of bottom and offer the same type of diving experience. So, if you find that one is too crowded, try heading to one of the other two bays.
  • Catherines Breakwater – On the south side of the breakwater in St. Catherines Breakwater, there is an extremely popular shore dive, but it’s best done on a high tide when you get the best water visibility. The breakwater itself is over half a mile long and home to a variety of flora and fauna. During the warm summer months, you can experience the breeding habits of the spider crab as it makes its way into shallow water to breed in large numbers.

If you’re interested in something a little different, there are always several drift dives that are run and operated by local dive companies on Jersey Island. These organized dives are great for beginner divers or anyone looking to experience a relaxed dive under professional conditions.

Jersey Island Shipwrecks and Dive Sites

Diving in the Channel Islands wouldn’t be complete without diving on one of the many shipwrecks which are scattered throughout the area. The treacherous tidal conditions, half-submerged reefs, and rocky shores of the Channel Islands have bought many experienced captains and ship owners into grief.

Being occupied for over five years by the Germans during World War 2, the Channel Islands are also home to a large variety of WW2 shipwrecks. So if you consider yourself a war history buff and diving enthusiast, there are many WW2 shipwrecks to explore around the islands.

  • SS Schokland – The SS Schokland is easily one of the most visited shipwrecks in the Channel Islands. The Schokland was a Dutch freighter that quickly sank in treacherous waters after hitting a reef in 1943 while under the control of the Germans. Sitting approximately 225 feet long and resting upright on the sandy bottom, the shipwreck is best dived at slack water. Every inch of the Schokland is covered in marine life, with huge clouds of fish cruising around the surrounding area. There are hundreds of small items to be found in the sandy water surrounding the wreck, including broken glass and china, and divers had even found perfume bottles and women’s shoes, which help to spread the rumor that there were French ‘ladies of the night’ on board the vessel when it sank. A rumor the German authorities always denied.
  • SS Kronwyck – Another German ship, the SS Kronwyck, was a small armed coastal freighter, also lies upside at a similar depth to the Schokland. The Kronwyck was allegedly bombed by two RAF fighters in 1942 and are rumored to be lying somewhere not far from the wreck, but divers haven’t managed to find their exact location yet. Maybe you could be the lucky diver to discover one or both of the RAF aircraft? The damage to the Kronwyck allows you to see into the two large boilers, and the wreck itself still has the large propellers and guns intact.
  • SS Princess Ena –Princess Ena was a large passenger ship that sank quickly after a fire broke out in the 1st class cabin area in 1935. Lying in about forty meters of water nine miles southwest of the Corbiere lighthouse, the wreck is home to a large amount of marine life, and the hull itself is split into three or four large pieces.
  • The La Mauve – Unlike many of the other shipwrecks surrounding the Channel Islands, the La Mauve was sunk on purpose by the Jersey Underwater Center about one mile off of Bouley Bay. The 60-year-old vessel was sunk in 1993 and is now a large artificial reef that attracts a huge amount of marine life. In addition, the small size of the La Mauve makes it an ideal shipwreck for beginners to dive as it’s almost impossible to get lost or disoriented while diving into the wreck.
  • M343 Minesweeper – Found on the Les Minquiers reef south of Jersey Islands, you’ll discover the German M343. It was one of four minesweepers based in the Channel Islands during WW2. Unfortunately, she was sunk in action and now rests in about 30 meters of water with her bow section broken off. Nevertheless, it’s a fantastic dive for anyone that’s interested in military history and also wants to experience some brilliant marine life.
