I did first time on Easter Sunday. Started at Regency gate, went up Donner Canyon to Middle Trail then up to Prospectors Gap. From there you go around back to Devils Elbow then up to the Summit. Fantastic view this day.
Also did in Nov 2003 with my son Zach on the much easier Mitchell Canyon route. We now live in Clayton so I hike and bike here alot now.
Started the new year off right, with a summit! Hiked up with good buddy Jeff 1-1-05
Update: 6th annual new years day summit 1-1-2010 about 28 total
nice place to hike... sure you can drive to the 360 degree views at the top, but there are also many varied trails in the park and you can design your own route... there are also some nice waterfalls in the northern section of the park... and the view from anywhere near the summit is still great, regardless of whether it's attained by foot or car...
I usually hike from Mitchell Canyon Road TH, through Eagle's Peak and then Prospector Gap. First time I hiked to the top in September 1996 and then I went back more often in 2002 training for Shasta. Nice hike, steep at times, beautiful views. One time while running almost stepped on a rattle snake, another time heard a mountain lion or a bobcat about 30' above me.
It's a good training place for bigger mountains.
Nice warm day with good views. Hazy in the distance and fairly uncrowded.
Beautiful weather! Nice long leisurely walk up to the top. Great views. I wish that people were not allowed to drive to the top as it would make for less crowds and preserve the natural beauty of the park.
Watch out for mountain bikers - almost got run over by three teenagers even though the trail is posted no bikes.
Didn't do Mt. Olympia. Great views of the Bay Area and nice spring flowers.
Followed Matthew's route directions for the most part, with some additional cross-country after leaving Mt. Olympia. A very fun hike. Trip Report
Did this as part of the Pacific Coast Trail runs event last June. Started up from the Mitchell Canyon parking lot-Deer flat road-Juniper trail-summit trail and then retraced my steps to Meridian ridge road-black creek trail-Coulter pine trail. The weather was awesome with a fog bank rolling over the western slopes and a limitless view to the north and east.
This was my first hike in CA.
Fun little hike...Great view from the top
Started out at the Mitchel Canyon parking lot and meandered towards Balck Canyon. Moved up onto the ridge and had lunch on top of Eagle Peak. From there followed the northwest ridge up to the saddle between the North Peak and the South Peak. Followed the trail around to the south side of the South peak and deviated to scramble up Devils Pulpit - slick rock but a good deviation. Clouds closed in quickly and visibility dropped to 10 to 20 feet. Total route was 8 miles up and we drove down because of the worsening conditions. Hiked with hyperbolictans.
Fantastic weather after weeks of snow and rain. Not a cloud in the sky, but a bit hazy, so the views weren't perfect. I did the top half of the Four Summits route (Mitchell Rock Trail, Eagle Peak Trail, Bald Ridge Trail, North Peak Trail, Ascent via Devil's Pulpit) but pulled a muscle on the way up, so had to abort the 2nd half. I did Juniper Trail, Deer Flat Road, Mitchell Canyon Road on the way back -- longer, but no ascents. That route wouldn't be so great for ascending, no break in the uphill, plus the view of Eagle Peak from far below is not nearly as fun as the view from on top! North Peak and Mount Olympia next time... The Devil's Pulpit scramble was quite fun, and is highly recommended!
This doesn't even count. Camping on the mountain, they close the park gates at 2000 hours. Drove to the summit in cold rain about 2200 and was alone. Talked on CB as far as Foresthill, Santa Rosa, San Jose, Fresno, ect. Good radio outpost. I didn't climb it, but for the faux paux, a raccoon woke me at 0300 walking on me in the back of my truck looking for food. YOW! Got MY attention! Bonked my head on the camper shell big time. My yelling freaked out the only other folks in camp.
Have summitted several times. A nice day hike starting from Mitchell Canyon. The views from the top are quite nice, reaching out to the Golden Gate Bridge and Farralon Islands.
Great day hike that's close to home.
As part of a charity bicycle event - I rode my bike up to the top of Mt Diablo. The last 100 yards of the road are 17% grade which is incredibly steep to ride up on a bike. The ride down was scary as I was trying not to go too fast. I think I wore out my brake pads!
It was cool. Also I felt like I wanted to do it again. I saw turkeys and cows. I saw coyote poop. I went inside the building. There were stuffed animals there.
As dictated to my mom.
Hiked this with Kim. Up in 2.5h. Fun hike, especially the lower parts. The top 1000' is a bit crowded. Not as many flowers as we'd have liked to seen, with all the cold & rain this spring. The paragliders were fun to watch.
On the way up we got a bit lost. Missed the Juniper trail and ended up doing a mile or so along the road, then connected with the summit trail around 300 feet below the summit.
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.
