Zandeiland 4 is a shallow reef site located within the Vinkeveense Plassen, a network of flooded peat lakes in the Netherlands. Accessible only by boat, the site is suited for intermediate divers who possess solid buoyancy control. Divers should be prepared for moderate currents and variable, often low, visibility conditions. Because clarity can drop to near-zero following rain or wind, carrying a torch is recommended for navigation and situational awareness. As facilities are not fixed on-site, divers should confirm boat access and any temporary restrictions with the site operator before planning a trip.

Exloerkijl is a freshwater site located within the Vinkeveense Plassen lake system. The topography features a combination of a recreational reef, a wreck, and artificial reef structures, providing clear navigation points for divers. With visibility ranging from 5 to 10 metres, the site is suitable for beginners building confidence in a controlled inland environment. Shore access is available, and the site is open for night diving, which serves as a practical setting for practising torch use and buoyancy. Divers should remain aware of variable currents and boat traffic while on the surface. As facilities are not guaranteed, visitors should arrive self-sufficient with all necessary equipment.

Het Weddermeer is a freshwater lake located within the Vinkeveense Plassen system, offering a practical environment for beginner divers. The site features a straightforward shore entry and calm, current-free water, which is ideal for practising buoyancy and technique. Divers can explore an artificial reef structure at depths ranging from 3 to 18 metres. Visibility is generally around 5 metres. Water temperatures fluctuate significantly throughout the year, ranging from 5°C in winter to 20°C in August. Due to the variable visibility and potential entanglement risks in the muck, divers should monitor their surroundings closely. A drysuit or thick wetsuit with hood and gloves is recommended outside of the summer months.

Zandeiland 4 is a freshwater dive site located in the Vinkeveense Plassen lake system. The site features an artificial reef structure accessible via a simple shore entry. Divers can expect depths ranging from 5 to 15 metres, making it a suitable location for building underwater experience. Conditions include moderate to strong currents and visibility typically between 5 and 10 metres, though this can fluctuate. Due to variable visibility, divers should monitor their depth and orientation closely. Facilities at the site include parking and toilets to support shore-based logistics. Water temperatures vary significantly throughout the year, ranging from 5 to 20 degrees Celsius.

Dankerner See is an artificial freshwater lake in Germany featuring an underwater park with various submerged objects. The site is suitable for beginners, with depths ranging from 6 to 12 metres and an average depth of 8 metres. Shore entry is available, and the site supports night diving. Visibility typically fluctuates between 2 and 7 metres. Divers can expect to encounter typical temperate freshwater fish and invertebrates consistent with the habitat, though specific sightings are not guaranteed. Facilities at the site include a dive shop, air fills, equipment rental, showers, toilets, and parking.

Nieuwediep is a freshwater site located in the Vinkeveense Plassen lake system. The topography consists of an artificial reef and a wreck structure, providing a controlled environment for divers. Depths range from 4 to 12 metres, with an average depth of 4 metres. Visibility varies between 3 and 10 metres. Access is via a shore entry located 50 metres from the shore. The site is suitable for beginners due to the lack of current. Divers should remain aware of boat traffic at the surface and use a surface marker buoy. Caution is advised around the wreck and artificial reef structures, which may have sharp edges.

Wippinger Kolk is a freshwater lake formed by sand extraction during the 1990s. Located within a forest, this site offers shore entries for divers reaching depths of up to 11 metres. The underwater environment is characterised by temperate freshwater habitats, which support a variety of freshwater fish and invertebrates typical of the region. Visibility at the site generally ranges between 5 and 10 metres, with mild currents present. Divers should be aware of potential entanglement hazards while exploring. This location is suitable for beginners and supports night diving. As a private lake, access is restricted to select divers, and visitors are expected to maintain the site's cleanliness.

Gasselterveld is a freshwater site located within the Vinkeveense Plassen, a network of flooded peat lakes. The site features a reef structure and reaches depths of up to 50 metres. While shallower sections are suitable for beginner divers, the significant depth requires careful planning and experience. Divers enter from the shore and encounter mild currents. Visibility at this location is variable, and cold water is a consistent factor, necessitating appropriate thermal protection. Boat traffic is a notable hazard at this site; divers should always deploy a surface marker buoy during ascent. As facilities are not confirmed, visitors should arrive self-sufficient with all necessary equipment.
