As an alternitive for offroaders I would recommend the old railway from Sälen to Särna. Its a perfect gravelroad for motorcycles!
This is one beautiful stretch of nice twisties along the Västerdalälven (West Valley River) from the skiing resort Sälen in the south to Särna in the north. Ride it smoothly at a speed of 110-120 km/h (keep it at 50-ish within the small townships along the river, though!) and you're in heaven! Combine it with the route from Sälen across the border to the Norwegian skiing resort Trysil. Ride safely, but have fun!
