The road ends in a meadow at the base of the mountain. Once there, leave your bike and look for a trail that climbs the ridge. Follow it through the timberline and up steepening switchbacks to the ridge crest. A few simple scramble moves may be required to gain the crest, but once on top, the walking becomes much easier for a little while. The final kilometer or so steepens significantly, and you’ll alternate between steep hiking and hand-and-foot scrambling, crossing a few false summits along the way. There is mild exposure in a few places, but no significant difficulties under dry conditions. Once on top, you may be surprised to find a concrete slab leveling the summit. This was once the sight of a repeater tower, but it has been removed.
