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.
