Cannon Ball Mountain

Embark on the Sampson Spring Trail, a difficult hiking route that challenges you with 4921 feet (1500 metres) of elevation gain over 11.4 miles (18.3 km). This demanding journey, which typically takes around 7 hours and 30 minutes to complete, leads you through high plains and stands of trees within the Nez Perce National Forest. You will experience expansive vistas from the summits of Mount Sampson and Cannon Ball Mountain, with the Seven Devil Mountains commanding the western skyline.

Planning your visit requires careful preparation for this challenging hike. The route includes primitive and unmarked sections, so you will need GPS navigation to stay on track. Much of the trail is unshaded, so be sure to carry plenty of water to stay hydrated throughout your adventure. This trail is also dog-friendly, allowing you to bring your canine companion along.

This route stands out for its dramatic changes in scenery, from exposed sections offering wide-open views to brief, shaded respites as the trail dips into the forested Blue Gulch. The journey to the twin summits provides a unique perspective of the surrounding wilderness, making it a notable trek for experienced hikers seeking a true test of endurance and navigation skills in a rugged environment.
