Route Climbed: more hiking/trail running than climbing Date Climbed: Jan 2001 (most memorable)
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.
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.
Route Climbed: Mt Olympia Trail; Back Canyon Date Climbed: Many
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.
