Idrija river pools at Zarog
The Idrija (not to be confused with the Idrijca) forms the Slovenia–Italy border in its upper course. Below the hamlet of Pušno (Kambreško), near the abandoned village of Zarog, it has three remote pools that hardly any locals visit: an upper pool with a waterfall about 3.9 m deep beside old mill walls, a small middle pool of 2.7 m, and a lower waterfall pool of 3.6 m beside a well-preserved mill ruin. Each large pool is ruled by one big, well-fed trout, smaller trout live in all of them and crayfish hide under the rocks. The dives are short and shallow; the challenge is getting there.
depth: 0–4 m
