A local favorite located about 12 miles north of town. It’s an easy day hike of eight miles round trip into a unique primitive area. The trail has a few steep upgrades, but they’re short ones. For your effort, you’ll be rewarded with an up-close view of the huge granite pillars for which the area was named, a forest of genuinely primeval Douglas fir, and a neat little trout stream.
See the Hiking section for the Humbug Spires, where there’s climbing in just about every grade. “The Wedge”, which stands at the head of the valley, is an alpine rock experience with mostly crack climbing.
