The river is long and plenty of spots to fish, this a day river part that holds good size brown trout and grayling, we normally start fishing at 6am in the summer and last season we would start a bit earlier at 4am. Having fished langån for a number of seasons it's a great river. it's long and there are plenty of places to fish. I have landed some of my biggest Grayling during the early stages of the season. During the time of June & July it's great for dry fly, using my home build #3 split with a light weight Hardy what else can beat that on a summers day. To get an idea of flies I normlly use a very small black at least #18 this imitations of a small black fly that we get during the summer months. One can also use a superpuppa - black or brown.
The water flow strength is not strong in some stretches you would need a good wading pole for other stretches.
There are at times hatches but when it starts it lasts for about an hour, after a shower or just before sunset.
There is one area where one can pitch a tent and have a rest, which is located down stream from the bridge
At times there are plenty of anglers trying to catch the big one, you can check out Jämtlandfishing Facebook page for updates.
