The highest of the rugged Boulder Mountains in central Idaho, Ryan Peak is composed of notoriously loose rock, which makes it a challenge to climb. The primary trailhead can be found at the end of National Forest Road 146; it brings hikers to the ridge located just southwest of the mountain's summit. Once here, it’s a beautiful and fairly easy walk to the top of the mountain. Designated camping spots can be found beside the North Fork Road, just before the trailhead, and there is also plenty of accommodation in the nearby town of Ketchum.
