This spur trail, solely used by hikers, is a challenging, often overgrown trail over steep, rocky terrain. The views are spectacular and it’s a unique experience, particularly at Table Rock, to be up close to the volcanic mountains. Most trail users do a one-way trip from the CA 29 Trailhead near Mount St. Helena to the Lower Oat Hill Mine trailhead, instead of the reverse, because the 3,200-foot elevation change is far easier as a descent. Try to do this hike between April and June, when the wild owers are blooming.
