Sometime in Oct 1992 (IIRC) I biked up Mt. Diablo which was pretty nice.
Only time I've been there was as the half-way point for a marathon that started from Clayton HS. Don't remember anything about the views, as it didn't seem too important after 13mi and 3500ft. Maybe I ought to drive up there sometime and enjoy it...
One of the hardest days of my life... All the 4000m peaks in the Alpes haven't been that cruel. We ran out of water in the searing californian sun...
Still a nice mountain!
I drove to the summit and did a looping trail that dropped down the north eastern side, looped around and back up to the summit from the south. ~7 miles I think - nice hike to do in the morning. Being January it was pleasantly cool up there, (even a bit of snow lying around in shaded areas:), and what made this trip memorable was morning low-lying fog encircling Diable and all the surround hills. All you could see was the tops, making you feel like you were above the clouds. Also saw paragliders taking off that day - very cool.
The climb itself isn't too spectacular, but the view from the top is incredible.
uh...this was a "vehicle-aided" ascent. :) I came up here with a European friend of mine, who thought he might paraglide off the peak. He had done it once off the western slopes, where afternoon summer westerlies induce nice thermals.
Never really even thought of climbing Diablo, even then, only in the winter. I often admire it from afar, though. Legend has it that Diablo was the second or third "most visible point" on earth, defined as acreage from which the point was visible. On an extraordinarily clear day you can see it from the Sierras, most points in the Bay Area, and probably from Sacramento to near Fresno.
First through hike was with Vladimir. The panoramic view from the summit encompasses nearly the entire length of snow-capped Sierra Nevada north to Lassen Peak of the Cascades. From the main summit you can see Pacific Ocean, San Francisco skyline, three bridges in the bay, and many, many more places. Go on a clear windy day in winter for the best view.
