Vipava at Kasovlje mill
The Kasovlje mill, first recorded in 1370, is one of the oldest on the Vipava; the mill itself is gone but its large, solid weir still backs up the river. Upstream the river forms a 3 m pool on the right bank and, about 20 minutes further, a 2.5 m pool on the left bank where a shoal of big but very shy fish lives. After about 40 minutes you reach the modern road bridge between Potoče and Brje, with old wooden bridge piles on both banks, and after an hour the bed gets too shallow.
depth: 0–3.5 m
