Sava Dolinka

The Zelenci spring pool, source of the Sava Dolinka, crystal-clear turquoise water surrounded by reed beds.

The Dolinka is the quieter of the two Sava headwaters, dropping out of the Tamar valley near Kranjska Gora into water so cold and clear it makes you reconsider your choice of waders.

About this water

The Dolinka is the quieter of the two Sava headwaters, dropping out of the Tamar valley near Kranjska Gora into water so cold and clear it makes you reconsider your choice of waders. Brown trout mostly, with rainbow trout again from the stocking programmes of an earlier decade. Smaller and more intimate than its sister river, and better for it in a way — this is pocket-water fishing where a good drift matters rather more than fly selection, which is either reassuring or slightly deflating depending on how much you enjoyed choosing the fly.

Seasons & zones
  • Trout 1 March → 30 September
  • Grayling 16 May → 30 November

    Slovenian common default: grayling 16 May – 30 November (lipan). Slovenia is permit and fishing district controlled — dates may vary by specific water. Always check the Ribiška Družina (fishing district) permit for the specific beat. The Soča, Idrijca, and Sava system hold world-class grayling alongside marble trout.
