#4 Mount Diablo

First time starting a hike from the Mitchell Canyon staging area. Used AllTrails: Mitchell Creek to Diablo Summit. Again, perfect weather, no wind, 60 degree temperature, clear sky. Could see snow on the Sierra Mountains, the Golden Gate Bridge, Sutro Tower, Mount Umunhum, pretty much everything. In the summer, this area can get super hot. Got to see clusters of lady bugs mating.
