The Hans Waldau is a wreck site located in Northern Germany, resting at a constant depth of 27 metres. This boat-only dive is suited for intermediate divers due to the combination of cold water, moderate currents, and an overhead environment. Visibility is limited to approximately 5 metres, requiring precise buoyancy control and navigation skills. Divers should be prepared for water temperatures ranging from 4 to 14 degrees Celsius, making drysuit use essential. The site presents specific hazards including entanglement risks and potential for strong currents, necessitating a methodical approach. Divers are advised to check local tidal windows to plan for slack water and to use a reel when exploring interior sections.

The Sophie is a wreck dive located off Northern Germany, resting at a depth of 28 to 29 metres. This site is suited for intermediate divers due to the moderate currents and limited visibility, which averages five metres. Divers should use a drysuit to manage water temperatures that range from 4C to 14C throughout the year. Navigation requires a torch to maintain orientation to the structure. Hazards include potential entanglement within the wreck, limited visibility, and active boat traffic at the surface. Divers must check current tables before planning a descent and ensure they maintain awareness during surfacing.

The Inger Klitt Wreck is a marine dive site located in Northern Germany. The wreck lies at depths ranging from 5 to 20 metres. Divers should be prepared for moderate currents and visibility consistently around 5 metres. Given the variable water temperatures, which fluctuate between 4 and 19 degrees Celsius throughout the year, appropriate thermal protection is required. The site is accessed by boat. Divers are advised to plan their route to swim into the current during the initial phase of the dive to facilitate an easier return. Local conditions should be verified before planning a trip.

Kaegnaes Faerge is a reef site located in the Alssund strait, characterised by strong currents that dictate the diving experience. The reef sits at depths between 8 and 12 metres, with an average depth of 10 metres. Divers access the site via a shore entry approximately 50 metres from the coast. Visibility typically ranges from 5 to 10 metres. Due to the significant current, this site is suited for intermediate divers with strong buoyancy control. Water temperatures fluctuate between 4C and 17C, requiring appropriate thermal protection. Divers should consult local tidal tables to plan their entry around slack water to manage the current effectively.

Dynte strand is a shore-entry reef site located in the Alssund area of the Little Belt. The reef structure descends to depths between 10 and 20 metres, situated approximately 100 metres from the shore. Divers encounter mild currents and visibility typically around 5 metres. Due to active boat traffic in the Little Belt, the use of a surface marker buoy is essential throughout the entire dive. Water temperatures fluctuate between 3 and 17 degrees Celsius, requiring appropriate thermal protection year-round. The site is suitable for beginner divers, though caution is advised regarding potential entanglement risks within the artificial reef area.

Osterholz is a shallow shore dive located in Northern Germany, offering a practical site for divers to gain experience. The site features depths ranging from 4 to 8 metres, with an average depth of 6 metres. Divers can expect mild currents and visibility between 5 and 10 metres. Due to the significant seasonal temperature fluctuations, which range from 4 to 18 degrees Celsius, appropriate thermal protection is required. The site is accessible year-round directly from the shore, making it a convenient location for regular practice. Divers should remain aware of local conditions, including the potential for low visibility and cold water temperatures.

Flydedok in Alssund is a challenging site defined by its wall and reef topography, suited for intermediate divers. Located in the Little Belt, the site is characterised by strong tidal currents that dictate the dive plan. Depths range from 15 to 18 metres, with an average of 16 metres. Visibility typically spans 5 to 10 metres. Due to cold water temperatures between 4 and 14 degrees Celsius, a drysuit is recommended. Shore entry is standard, and the site is supported by facilities including air fills, showers, and changing rooms. Divers must monitor boat traffic and use a surface marker buoy throughout the dive.

Alssundbroen is a drift dive site located in the Alssund, Denmark. Divers can explore the bridge piers and the surrounding slope, which features a bottom covered in mussels. The site reaches a maximum depth of 11 metres. Access is via a shore entry. Conditions are variable, with visibility ranging from 1 to 10 metres and water temperatures fluctuating between 4C and 17C throughout the year. Due to the nature of the location, divers must be aware of strong currents, active boat traffic, and the presence of local fishermen. This site is suitable for beginners, though caution regarding surface hazards is essential.
