Hikers explore Grassy Top and Hall Mountain

Less than a mile south of the trailhead you will arrive at a crossroads. Taking a right  onto Forest Service Road 540 and continue to the summit of Hall Mountain, where you are rewarded by views several thousand feet above scenic Sullivan Lake. The five-mile traverse may lather up quite a sweat, but the vantage is well worth it. The terrain is challenging and is home to rugged wildlife like bighorn sheep, grizzly bears, elk, and cougars.


Hall Mountain is in the center of one of the largest tracts of unprotected wilderness directly adjacent to the Salmo-Priest Wilderness Area. This hike is an excellent opportunity to see the habitat of the grizzly bear and offers a great introduction to the Columbia Mountains.


Getting there:

From the north end of Sullivan Lake travel East on Forest Service Road 22 for 3.25 miles, to turn right onto Forest Service Road 500 (Johns Creek Road). Continue for 7 miles to the trailhead. There is parking for only three vehicles; the road is open from July 1 to August 14.
