Les Ecrehous islands are a series of offshore reefs located approximately 9656 metres from the Jersey coastline. These sites feature extensive kelp forests and varied reef topography, with depths ranging from 5 to 15 metres and an average depth of 10 metres. Due to the location, boat access is required. Divers should be prepared for strong currents, rip currents, and surf conditions. The site is suitable for beginners, though the dynamic water movement necessitates careful planning. Guided tours and boat charters are available to facilitate visits to these islands, which are a popular destination for those exploring the North and East Coast of Jersey.

Break Water, located between Bouley Bay and St Catherines, offers a shore-entry dive featuring a mix of natural reef and artificial structures. Divers can expect an average depth of 10 metres with visibility ranging from 3 to 9 metres. The site is suitable for intermediate divers, though caution is required due to potential boat traffic and overhead environments. Water temperatures fluctuate between 10C and 18C throughout the year. Species recorded around this area include wrasses, lumpfish, squat lobsters, pipefish, various crabs, and sea stars. Facilities at the location include parking, toilets, showers, changing rooms, a rinse station, and access to air fills and guided tours.

St Catherines, located on the north-east corner of Jersey, offers shore-based diving along the breakwater. The site features a mix of reef, artificial reef, and seagrass habitats with depths ranging from 5 to 12 metres, averaging 8 metres. Divers can expect mild currents and visibility varying between 0 and 20 metres. The topography consists of large boulders providing shelter for various marine life. Facilities at the site include parking, toilets, showers, changing rooms, and a rinse station, with dive shops and boat charters available nearby. This site is suitable for beginners and supports night diving, with typical dives lasting around 50 minutes.

Les Laveurs is a reef site located between Bouley Bay and St Catherines, Jersey. This shore-entry site is suitable for beginners, with an average depth of 6 metres. Divers and snorkellers can expect variable visibility ranging from 0 to 20 metres. The site is subject to moderate currents and occasional surf, requiring careful planning. Marine life recorded at the site includes common sightings of pipefish, crabs, shrimp, and sea squirts. Less frequently, divers may encounter wrasses, squat lobsters, conger eels, spirographs, grey sea slugs, rock crabs, brittle stars, sea stars, snails, and European green crabs. Facilities at the location include toilets, showers, and the availability of guided tours.

The Shockland is a 68.5-metre-long, 10-metre-wide shipwreck located in Brittany and Normandy, France. Originally a Dutch vessel used for troop and cargo transport during the war, it sank in 1943 after striking a reef. The wreck lies upright and remains largely intact, with cargo holds still containing cement bags and steel beams. Divers can explore this site at depths ranging from 20 to 30 metres, with an average depth of 25 metres. Access is by boat only. Due to moderate currents, low visibility, and the depth of the wreck, this site is suitable for advanced divers. Hazards include decompression, entanglement, and nitrogen narcosis.

Rigdon Bank is a wall dive featuring gullies and bombies along the south west coast of Jersey. This site is suitable for advanced divers due to the moderate currents and tidal nature of the area, which requires diving during small tides. Depths range from 10 to 40 metres. Access is strictly by boat, and the site is subject to strong currents. Water temperatures fluctuate between 10C and 18C throughout the year. Local facilities including air fills, equipment rental, guided tours, and boat charters are available to support diving activities at this location.

Guillot Caves at Rigdon Bank offers a complex environment combining cave penetration, reef topography, and drift diving. Divers can explore depths ranging from 7 to 20 metres, with visibility typically between 10 and 30 metres. The site is suited for intermediate divers due to the overhead environment, sharp rock formations, and strong currents. Entry requires careful planning around the tidal cycle to manage current strength and avoid surf conditions. A boat is recommended for all entries to bypass the shore break. Divers must maintain precise buoyancy and situational awareness to navigate the caves and mitigate entanglement risks.

The Brittany & Normandy Wreck is a multi-faceted site featuring a wreck, reef, and kelp forest located 1900 metres offshore from Cherbourg. The site spans depths from 12 to 33 metres, with an average depth of 9 metres. Divers must access the site by boat to avoid dangerous surf and shore breaks at the coastline. Conditions are characterised by moderate currents and variable visibility, requiring strong buoyancy control and careful monitoring of tidal flows. Water temperatures range from 9 to 15 degrees Celsius, necessitating a 7mm wetsuit in summer and thicker gear with gloves and booties during other seasons. This site is suitable for intermediate divers.
