Nanoščica at Cenetov mlin
The slow Nanoščica stream meanders across the marshy plain between Nanos and Postojna before joining the Pivka just before Postojna Cave. Remains of old mills survive, and their weirs still deepen the stream enough for swimming and diving; around Cenetov mlin east of Landol there are many meanders, oxbows and small ponds. The deepest point is a pool of about 3 m by a wooden jetty used as a jumping platform; elsewhere the clay channel averages 2 m, carpeted with algae and fallen branches, with shoals of small fish just below the surface.
Tiefe: 0–3 m
