About the river

As a glittering diamond chain the Trysil river runs through a landscape of mountains and forests on it's way south where it crosses the Swedish border. As a result of its nearness to the sources and calcium rich soil in the north, the Trysil river has an excellent water quality and a strong stock of local brown trout and grayling. The slow moving parts of the river keep good whitefishes and pikes as well.

The fishing activity is well organized and easily accessible. With the fishermen's different needs and wishes in mind, the organizers also want some parts of the river reserved for groups with special interests, for instance zones for fly only. As a consequence of this, Gjerfloen Flyfishing and the fly fishing zone was initiated. Available fishing guide and cabins for renting.

At Plassen, 10 km from the Swedish border, Gjerfloen Fluefiske is reserving a 7 km part of the Trysil river for those who have come to the conclusion that 3 important elements in life are: grayling, nymphs and dry flies.

Description of the fly zone

Within the fly fishing zone you can find both lazy, slow moving waters and faster streams with resting places for the fish behind big stones. Most of the river is wadeable on normal water level. The Trysil river is within the fly zone, 50 to 80 meters wide. Along the banks there are paths on both sides of the river. These are made also to conserve the original vegetation as much as possible.

Fly fishing season

The normal fly fishing season lasts from the middle of June till October. However, in 2000 the last fly caught grayling was landed the 9th of December. June and September are the favourite months amongst many flyfishermen.

Anyway, - weather, temperature and water level strongly contributes to influence the point of time for the insect activity which again is generating conditions for the ultimate grayling fishing. Perfect conditions may occur at any time throughout the fishing season. The important thing is here as in all sorts of fishing: To be at the right place at the right time!



There are signposts at 8 parking places with INFO boards and paths down to the river.


The Trysil river contains brown trout, grayling, whitefish (might be very big, +2 kg), pike, burbot, some perch and minnows. The grayling is the dominating specie and occurs in large numbers.

Brown trout and grayling, maximum size and bag limit

Our goal is that before long we shall have a larger number of big fish within the fly fishing zone. There is only one prescription to reach this goal: The fish must be allowed to live long enough! Gjerfloen Flyfishing has therefore introduced special rules for bag limit and size. Bag limit is for brown trout and grayling. You may kill only one fish a day, maximum size is 38 cms.



Fishing for grayling organized in this way, is the first of its kind in Norway. The scientists have therefore signaled that they want to follow up the project with research. Material from these studies will in some time also be available for the fishermen.

Limited number of fishermen

To achieve a pleasant fishing and wildlife adventure it is, in our opinion, important to limit the number of fishermen. Gjerfloen Flyfishing will for this reason sell maximum 20 fishing licenses pr day. The license is valid from 0800 in the morning to 0800 the next morning. Fishing license: NOK 170 pr day

Special rules

Fly only. Fly fishing practiced with rod and the casting weight made by the fly line. The hook shall be barbless or the barb must be pressed down with a pair of tongs.0
