Idrijca at Dolenja Trebuša
At Dolenja Trebuša the Trebuščica joins the Idrijca, creating several 3–4 m pools and leaving the wreckage of an old bridge, whose concrete blocks and iron are now hideouts for fish. In summer the Idrijca is warm and clear with a weak current, so this is an easy, shallow dive also used for beginner courses. Upstream of the road bridge the river is only about 1 m deep for 500 m, better for snorkelling, but a bigger fish waits behind every large rock. The sheet especially recommends it as a freshwater night dive.
Tiefe: 0–4 m
