Karhunkierros Trail, Finland Finnish Lapland is renowned as a winter destination, with magical displays of aurora borealis and a fascinating ancient Sami culture. It’s also home to the 82-kilometer (51-mile) Karhunkierros Trail, the most well-known long-distance walk in Finland. It’s a route best explored in summer, when the nights are bright and the forests verdant. The path begins in Hautajärvi village in Lapland’s Salla and ends at the Rukatunturi Fell in Kuusamo, taking four days, depending on the weather, which can change rapidly. Passing through Oulanka National Park, there’s a sense of being in a true wilderness, where trout leap from rivers and lynx and wolverines prowl through the pines.
