Gradaščica

Gradaščica — Gradaščica Creek

Huchen on Ljubljana's doorstep, which is a stranger sentence than it sounds — the Gradaščica runs down out of Polhograjsko hribovje and into the capital's western suburbs carrying sulec alongside brown trout and grayling.

Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

About this water

Huchen on Ljubljana's doorstep, which is a stranger sentence than it sounds — the Gradaščica runs down out of Polhograjsko hribovje and into the capital's western suburbs carrying sulec alongside brown trout and grayling. Not a wilderness river by any stretch; more a reminder that this fish doesn't need remote water, just clean water, which the Gradaščica manages to be despite the houses along its banks.
