To see them, park at the Hoodoo Creek Campground. The hike begins on a gravel road through the disused portion of the campground, then crosses a footbridge and takes a trail through the forest. The climb is gradual for a while, but becomes quite steep before reaching the end. Nearing the hoodoos, the trail forks to an upper and a lower viewpoint. The distance is not great to either one, so you can easily check out both of them. Fine gravel on the trail is loose underfoot, so trekking poles can help greatly on this final portion of the hike.

There are several good spots to soak in the view from this open hillside. In addition to the hoodoos, you can see to the stream in the valley bottom and toward the mountains on either side. Simply return the way you came, and views are even better in the reverse direction.
