The Big Sky State has one trail, located in Flathead National Forest. It’s the northernmost and most isolated on the map, making it one of the rarest of the 56 trail badges. The craggy trail through the pine forest has some difficult technical sections that require rock-crawling experience. The park is less than two hours north of Missoula and about five and a half hours south of Calgary.
