On Saturday, November 26, 2011, I joined a Hikers & Company Meetup that did a loop hike to the summit of Mt. Diablo. We left Sacramento at 7:38 a.m. and arrived at the Mitchell Canyon Interpretive Center at about 8:10 p.m. I ran my iPhone's Map My Hike app to track the trail. The new phone's battery nearly died by the time I finished at about 4:15 p.m. We spent about 40 minutes at the summit walking through the museum and eating lunch. We saw a couple of other large groups on the trail at the same time we were on it, in addition to a few small groups and some cyclists, who must generally use the automobile road. he trail is quite separate from the hiking trail.
