Casa Diablo Mountain

California > Sierra Eastside > Mammoth Lakes Area


Casa Diablo Mountain is situated in the middle of the Long Valley Caldera, with spectacular views of the White, Glass, and Sierra Nevada Mountains.
There are only a few routes here, but development is taking place. Half the climbs are north facing and the other half west facing.
This is a great mild weather climbing spot that is lower than the Mammoth area climbs and sits a bit higher than the Owens River Gorge.
There are a fair number of easy and moderate climbs here.

Getting There

From the 395 head east on Benton Crossing Rd. Drive 18 miles and turn right on a dirt road (3S02) (The Mammoth Area Rock Climbs guide says there is a sign, but it is very weathered)

Drive for a few miles (6 or 7ish) on a great dirt road (one of the best I have been on in the Sierras)Keep left at the first T (still 3S02) Continue on 3S02 and at the second T stay right (still 3S02) ^Check out the photos below of these turns ^

You will now be running parallel to Casa Diablo Mountain, Turn left between two trees on 04S134. Continue on a washboarded road and take the left turn onto 04S134F There is a small round parking area.

From the parking you can see a few climbs, these climbs are not in the guide book, the ones in the guide book are on the left side of the rocks.

[Hide Comment] When driving it can be easy to miss the first left turn after about a mile. If you take the right fork, you could find yourself all the way at pocketopia. Apr 30, 2012

[Hide Comment] Lots of drilling happening out there! Loud... Happy to finally see some route info. Oct 13, 2013
[Hide Comment] Great place with stellar views, and a nice break from the crowded boulders in bishop and the owens river gorge. From what I climbed its super super fun stuff and nice amount of protection (bolted almost gym like, didn't mind it a bit.) Reminiscent of Joshua Tree style rock. Jan 3, 2014

[Hide Comment] As of Nov 2016 road 134 is not wash boarded, it's more like washed out. Better have a high clearance vehicle, not sure even a Subaru would make it without damage. Nov 10, 2016
[Hide Comment] One of my favorite spots, now is the perfect time to be out there. The last little road is kind of dicey, but not too bad if you're careful, just straddle the ditch. It looks like there's been some new development out there on the big green wall. If anyone knows who's been putting those up, I'd like to talk to them. I've got my eye on some potential routes nearby, want to make sure I'm not snaking them. I've also been bolting some other stuff farther up canyon, details to come once I've got all the FAs.

[Hide Comment] Also, can I petition to move area this under Sierra Eastside > Eastern Hills instead of Mammoth area. Seems like a better fit to include this with Benton. The Sherwin plateau could be moved too. May 4, 2017
