HMS Brazen is a Royal Navy destroyer wreck resting at depths of 30 to 35 metres off the Sussex Coast. This site is suitable for intermediate divers with advanced certification. Access is exclusively by boat, and the wreck structure presents potential entanglement hazards, requiring careful buoyancy control. Visibility typically ranges from 5 to 10 metres. Water temperatures vary between 8 and 18 degrees Celsius, making thermal protection such as a drysuit or thick wetsuit necessary throughout the year. While currents are generally mild, they can fluctuate, and divers should remain aware of their surroundings and monitor bottom time closely due to the depth.

The Loanda is a wreck resting at depths between 20 and 23 metres off the Sussex Coast. Accessible only by boat, this site is suited for intermediate divers. Visibility is highly variable, ranging from 3 to 20 metres, and currents are generally mild. Divers should maintain good buoyancy control to navigate the structure, as the wreck presents entanglement risks and sharp edges. Water temperatures fluctuate between 8 and 18 degrees Celsius throughout the year, making a drysuit or thick wetsuit necessary. Always check local visibility reports before planning a dive, and carry a wreck reel for safety.

UB-78 is a World War One German submarine wreck resting upright on the seabed off the South East coast of the United Kingdom. The vessel remains largely intact, offering an opportunity to explore naval history at depths between 25 and 28 metres. This site is suitable for intermediate divers who possess solid buoyancy control and wreck awareness, as the structure presents overhead environment hazards. Access is by boat only, located over 10 kilometres from the shore. Divers should expect moderate currents and visibility ranging from 5 to 10 metres. Typical dive times are approximately 40 minutes, and it is recommended to time dives around slack water to manage currents.

HMS Hermes is a shipwreck located off the coast of France near Calais, resting at depths between 40 and 57 metres. This site is strictly for technical divers, requiring trimix or rebreather capability and wreck qualification. The wreck features internal overhead environments that present entanglement risks. Divers must navigate strong currents, making precise timing with slack water windows essential. Visibility varies significantly from 10 to 40 metres. Given the water temperatures ranging from 8 to 13 degrees Celsius, a drysuit is recommended for all dives. Proper gas planning and decompression management are critical due to the depth profile and the nature of the wreck.

Botany Bay on the Sussex Coast features a shallow reef environment characterised by white chalk stacks and cliffs. Snorkelling is best conducted at mid-to-high tide around the base of these cliffs, where depths range from 1 to 8 metres with an average of 4 metres. The chalky seabed can occasionally reduce visibility to between 3 and 8 metres. Divers and snorkellers may encounter rock crabs, European green crabs, common sea stars, snails, and the occasional catshark. The site is accessible from the shore, though users should be aware of potential surf conditions. Facilities including parking, showers, and a cafe are available nearby.

Cran aux Œufs is a rugged rocky cove situated at the base of the Cap Gris-Nez cliffs in France. This shore-entry site features an underwater topography dominated by large sandstone boulders and kelp forests. It is suited for intermediate snorkelers due to the presence of moderate currents, surf, and potential rip currents. Visibility is variable, ranging from 2 metres upwards, and water temperatures fluctuate between 9C and 19C throughout the year. Divers and snorkelers should be prepared for cold water conditions and sharp rock formations. Parking is available near the site for easy access to the shore.

Cran d'Escalles is a shore-entry snorkel site located at the base of the white chalk cliffs of Cap Blanc-Nez. The site features a chalk reef ecosystem with depths ranging from 1 to 5 metres, averaging 3 metres. Conditions are variable, with visibility typically between 3 and 10 metres depending on swell and weather. Divers and snorkellers should be prepared for moderate currents and surf, which can impact visibility. Water temperatures fluctuate throughout the year, ranging from 9C in late winter to 19C in August. Parking is available for visitors. Due to the environmental conditions, this site is best suited for intermediate snorkellers.

Caulonia is a shallow shore dive located on the Sussex Coast, suitable for beginners looking to practice skills in a relaxed environment. The site features a reef structure that provides a focal point for navigation. Water temperatures fluctuate between 9 and 18 degrees Celsius throughout the year, necessitating a well-fitted wetsuit. Visibility is variable, offering divers the opportunity to manage changing conditions. As a marine environment, the site supports a variety of temperate reef fish and invertebrates typical of the region. Divers should arrive self-sufficient with all necessary equipment, as on-site facilities are not confirmed. Always check local visibility and current conditions before entering the water.
