The Komoot tour that utilizes the Sampson Spring Trail is rated as difficult. While the Sampson Spring Trail itself is considered a 'blue difficulty' (moderate) singletrack, the full Mount Sampson and Cannon Ball Mountain Hike is a challenging adventure for experienced hikers. It involves some off-trail sections and requires GPS navigation due to primitive and unmarked parts of the route.
The Komoot tour for the Sampson Spring Trail, which includes summiting Mount Sampson and Cannon Ball Mountain, is estimated to take approximately 7.5 hours to complete. This duration accounts for the 18.3 km (11.4 miles) distance and nearly 1500 meters (4921 feet) of elevation gain.
The route primarily follows a singletrack trail. You will encounter exposed sections, and the trail dips into the forested Blue Gulch, offering brief relief from the sun. Much of the route is unshaded, so be prepared for sun exposure. The path explores high plains and tree stands, leading to the summits.

Given the exposed sections and high elevation, the best time to hike is typically during the warmer, drier months when snow has melted and conditions are favorable. Summer and early fall would likely offer the most accessible and enjoyable experience. Winter hiking would present significant challenges due to snow and potentially extreme weather.
As the Sampson Spring Trail is located within the Nez Perce National Forest, it's advisable to check the official U.S. Forest Service website or contact the local ranger district for current information on any required permits, entrance fees, or specific regulations that may apply to hiking or parking in the area.
