Bruksleden trail from Surahammar to Halstahammar Västmanland, Sweden offers a 12km trail that's perfect for birding, hiking, and walking. The trail is moderately challenging and takes about 3 hours to complete on average. You'll wander through a mix of natural and cultural landscapes, following orange markers on trees and poles. Just watch out for some road walking towards the end of the trail!

I walked there in winter and in summer. It's always beautiful, no matter when you go there.
