The Salmon Butte Trail #791 is one of the more popular trails in the Salmon-Huckleberry Wilderness, but the hike got longer by about 2 ½ miles and gained more elevation with the decommissioning of FR 2618 in 2010. Like other Salmon-Huckleberry Wilderness trails, the optimal time to visit is on a clear day in June, when the rhododendrons, bear-grass, and other wildflowers are in full bloom and the views from the summit of Salmon Butte stretch from Mount Rainier to the Three Sisters. After the initial road walk, this is mostly a shady forest hike with a few small clearings supporting microhabitats and limited views – until you get to the top, that is.
