Wow those are really tall mountains! Thanks for writing the height in meters as well haha. I just looked up the height of the tallest mountain in Sweden (Kebnekaise) is only 2100 meters, not very impressive.

There is a trail in the north of Sweden called Kungsleden, it is quite famous and the length is around 400 kilometers and you cross through 4 national parks. It’s quite famous and some of my friends did the trail and said it was really beautiful
