A balanced Scottish river profile. Early season nymphs and spiders, then more dry-fly and emerger fishing as hatches strengthen on steadier glides and richer water.

About this water

Not to be confused with the more famous salmon Carron in Wester Ross, this Carron is the Stirlingshire one — the river that runs through Denny and Larbert before joining the Forth below Grangemouth. It has had a hard industrial past and the lower reaches still show it, but the upper and middle river above Denny is a genuinely pleasant little wild trout stream, fished by local clubs and holding a good head of small to modest brown trout. It's proof of the thing Scottish anglers already know — that even the Central Belt's forgotten rivers can reward a patient fly fisher with a few hours of honest fishing if you know where to go. Day ticket fishing through Denny & District Angling Club and similar.
