This dive site, Seen Widdauen in Langenfeld, Germany, is a unique freshwater destination formed from a former gravel pit. While the primary diving area has a maximum depth of 11 meters and an average of 5 meters, the broader Widdauen Lakes complex offers depths reachable up to 27 meters. The site boasts excellent infrastructure, including toilets, barbecue areas, shelters, and ample parking, making it convenient for divers and families. Navigation underwater is typically straightforward in a calm lake environment.
Divers can encounter a variety of freshwater species, including different types of carp, perch, and walleye. The lake is also home to numerous freshwater crayfish, eels, and notably, large catfish. The shallow shore areas are characterized by lush aquatic vegetation, providing hiding spots for smaller creatures and an interesting backdrop for macro photography.
The best time to visit Seen Widdauen for diving is typically during the warmer months when water temperatures are more comfortable, although with appropriate drysuit gear, it can be dived year-round. Its shallow average depth makes it particularly suitable for beginner divers, training sessions, and snorkeling. Freedivers will also find the calm waters and varying depths (especially if accessing deeper parts of the lake) appealing. The comprehensive infrastructure makes it an ideal spot for a day trip with family or a dive club outing.
