In deep pools and dark water, silhouette and contrast do the work colour cannot. A fly that reads as black against depth is enough. Fish it broadside, hold the swing, let it hang at the dangle — that is when the best fish take.

About this water

The water quality is exceptional and the trout know it: they feed selectively, inspect your fly with irritating thoroughness, and refuse anything that doesn't convince them completely. Premium water with restricted access — guided days or private invitation. If you want to test your dry fly skills against properly difficult fish in a Scandinavian setting, this is the river.

Sea trout here

Premium chalk-stream water with sea trout potential. Not in the headline sea-trout-destination conversation but the quality of the fishing and the fish is exceptional.
