The trail up Kerby Peak from the White Creek Road Trailhead is steep and challenging but well graded and rewards your efforts with wonderful views of the Illinois Valley, the Siskiyou Crest, and beyond. The trail apparently dates back to 1915 (or earlier) and was heavily used when a fire lookout sat atop the peak. The lookout was burned in 1966 and a new trail was constructed in 1978 but soon fell into disrepair. It was revived by the Bureau of Land Management (BLM) in the late 1990s when they restored both the trail and its current trailhead on White Creek Road. We hiked it for the first time during the snowless winter of 2015 (post). Today we thought we’d see what it was like when the weather was warmer (but not too warm) and any snow was (almost) gone. This was one of those days when we climbed out of a valley mired in fog into blue sky – and big views – above. Great views and an equally great workout (6.4 miles round-trip; 2,600 feet of elevation gain).
