HTSV-See Schönbach (Steinbruch Winkel)
The former quarry 'Steinbruch Winkel' at Schönbach near Herborn is the training lake of the Hessian diving federation (HTSV). Its bottom steps down to about 30 m, and visibility ranges from 2–3 m to 7–8 m or more depending on season, rain and traffic. The site has been open all year since the 2005/06 winter season, with reduced winter hours. Access is organised through the federation's duty instructor rather than a commercial base.
depth: 0–30 m
