FATMAP difficulty grade
Beautiful mountain and forest hike.
Clean river water and a big chance of spotting reindeers.
Trail is marked but I highly recommend bringing your own paper map.
You can bring your own tent and camp wherever you want.
Or you can pay a little to stay in the huts.
In summer/autumn you can hike this route, and in winter you can tour with skis (if you do it in winter you have to know what you are doing).
