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.

Kollund Lillestrand is a shallow muck dive site located in the Alssund area of the Little Belt. Divers access the site directly from the shore, entering via a gradual beach slope. The site reaches a maximum depth of 9 metres, with an average depth of 5 metres. Conditions are generally manageable due to mild currents, though visibility can be highly variable. Water temperatures fluctuate between 4C and 17C, necessitating appropriate thermal protection. The seabed consists of sand and silt, providing a habitat for various temperate marine life and invertebrates. This site is suitable for beginners and offers convenient access with nearby parking and toilets.

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.

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.

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.

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.

Wreck S103 is a boat-access dive site located in the Alssund, Denmark. The wreck rests at depths between 20 and 33 metres, with an average depth of 26 metres. Divers encounter moderate currents and limited visibility of approximately 5 metres, necessitating the use of a torch and a reel. Due to the depth and cold water temperatures ranging from 4 to 14 degrees Celsius, this site is suited for intermediate divers. The environment supports temperate marine life typical of the region, including various reef fish and invertebrates. Divers must manage nitrogen narcosis risks and use a surface marker buoy due to active boat traffic in the strait.
