>>119693Fishing is possible. Pic related. We did not catch much though. And only small fish. As a general rule in the Scandinavian mountains fishing is best around the tree line. Abisko to Kebnekaise is way above the tree line.
If you want to fish I would recommend the more southern parts of Kungsleden or perhaps further north in Norwegian Finnmarken where fishing is excellent (arctic char and trout).
I would certainly not recommend driving because of the distance. It is almost 2500 km each way and there are no highways beyond Stockholm so from there it is 80 km/h the rest of the way. If you are only 1 or 2 persons it is also expensive: 2 x bridge (75 eur) + 2 x ferry (100 eur) + 5000 km (petrol: 700 eur) = 875 eur. Depreciation of the car not included. My guess is that you can buy plane tickets for that amount and in addition save 40 hours driving or so. It is easy going from Kiruna to Abisko or Nikkaluokta by train or bus.
Another option is to take the train from Berlin to Copenhagen and further north to Kiruna. They have comfortable sleeping wagons and it is around 25 h from Copenhagen. When I went there I paid around 175 eur for a return train ticket from Copenhagen to Kiruna.
If you go by car I would not care much about finding a place to sleep. Just take any road away from the main road, then drive 1 km and find a place to park your car and pitch your tent 100 m into the forest. This is perfectly legal in Sweden.
If you would very much like very deserted hiking I can recommend a few places near Abisko where you can hike for days without seing anybody. And the scenery is about the same as along Kungsleden and the fishing is way better.
I'll monitor this thread.
