The Three Country Cairn is where the borders of Finland, Sweden, and Norway meet, making it the world's most northerly tripoint. This unique spot is marked by a yellow-painted concrete cairn in Lake Goldajärvi, surrounded by beautiful Nordic landscapes. Visitors can take a boat trip from Kilpisjärvi in Finland during the summer months to reach the cairn, or then go for a hike through the Malla Strict Nature Reserve. It's a cool place to check out if you're into exploring remote border crossings and enjoying the great outdoors!
