Enjoyable dayhike (Eagle Peak-Diablo-Devil's Pulpit-North Peak-Olympia) out of Mitchell Canyon. The scramble up to the main summit via Devil's Pulpit is fun class 2-3; the XC route between North Peak and Olympia is less so.
I started from Devil's Elbow right below the summit and descended to Prospecter's Gap between the main and North peaks. From there I followed the fireroad up to the North Peak. It gets really steep and loose right before the summit. I foung the highpoint right next to a huge antenna and stood on top. From there I followed the ridge straight down towards Mt. Olympia. I had to detour around a huge rock wall about halfway down (from the bottom it didn't look as bad). About 10 minutes of difficult bushwacking brought me to a saddle where I climbed some bad rock to a point that I though was the summit. Had to continue anothe 100 yards to the real summit. This route is supposed to be class 3 if you keep to the ridge, but what I did was probably difficult class 2 downclimbing. Found a geocache box at the top (not an actual summit log). Followed trails back to my car. I saw only 1 other person between North Peak and Mt. Olympia, even though it was a Saturday with pretty good weather.
What a beautiful day. This is a fun day trip. The trail became indistinct in a few places as the grass was overgrowing the trail even with the low rain year we've had. Shows how little this trail is used. Also there were a couple of washouts along the section of trail between Olympia peak and the North Summit. Met fellow SPer Don Bender and his two sons on the North Peak. Hiked to the South Peak with them.
A nice climb on Superbowl Sunday. Didn't see a soul until reaching Prospector's Gap. According to my GPS, the round trip was 12.3 miles and 4,100 ft. including a side trip to the North Summit
I hiked this peak 3 times through various approaches which included Mt. Olympia trail and the road. It was certainly tough and strenuous but not too pleasant due to sun/heat exposure. I will try it again this winter.. hopefully it is nicer in cooler weather.
I did my most recent climb on my mountain bike. Went to the top on the summit trail and rode down the long, winding road. Riding down was very fun.
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.
