The majority of the Quarry is west facing, so the seasons dictate when is the best time to climb. In the summer you can climb to noon, in the winter climb in the Agony Arch area in the morning and the rest of the crag in the afternoon. When it is really windy a few climbs in Slab City are protected. This is a popular area for dirt bikers; on the weekends it can get really busy and noisy. There are so many climbs here that crowds are sparse.

The granite is very high quality and has many unique features due to the early quarrying operations. A lot of the climbs have key holds reinforced with glue and more than a few climbs have holds drilled or chipped. Most of the routes are over 100 feet, some with as many as 24 bolts. This is mostly a sport climbing area, with chains or other suitable anchors at the top of almost every climb. Many routes can be done with 10-12 quickdraws, though.

This place is a great place to spend an afternoon, but due to its close proximity to Riverside and other surrounding cities, there is a lot of trash, junked cars, and random other pieces of junk that no one wants anymore. If you are looking for a beautiful, quiet place to climb, this is definitely not it. If you are looking for an afternoon of fun climbing on good rock this is your ticket.


The Quarry is on private property and driving into the quarry is not allowed - please park on the street. The land owner has a mutual understanding with the rock climbers and allows us to climb here. Please be respectful and keep the noise down, pick up your trash (I know it seems kinda pointless sometimes), and smile and be polite to the police officers when they come through. The more you do, the less likely it is for this place to be closed.


Although there are lots of fast food restaurants nearby the preferred choice is the nearby TJ's Tacos which is just north of the 60 Freeway on the right-hand side (as you drive to the crag) which has amazing tacos (try the carne asada tacos) for $1.35 they are amazing.


A lot of the route beta (# of bolts anchors at the top, and locations) are taken from the guide book, for the sole purpose of providing information and developing further interest in the area. Please contact Louie Anderson ( to get a copy of the guide book. This are has been very well developed, and most of the cost has been paid for by the route developers. 100% of the proceeds of the guidebook go towards paying for bolts and anchors at the Riverside Quarry. The cost of the guide book is $19.95.

Getting There 

From Los Angeles and points west: Take the I-10 Freeway East, South on I-15, East on the 60. Exit Valley Way. Turn left; the cliffs are now visible to the NE. Turn right on Sierra, and then left on the dirt road after the housing development.

From Redlands and points east: Take the I-10 West to the I-215 South, then West on 60. Exit Valley Way/Arnold, turn right then another right on Sierra.

This route is an incredible and long moderate route, even by quarry standards. The route has two distinct cruxes, one at the bottom and one at the top, separated by sixty or so feet of fun climbing on good holds in stellar position. The climb starts on small holds under a bulge. Traverse right and up, then around the bulge to jugs. Continue over a series of ledges on good holds while the climb edges closer to the left-hand arete. After a nice rest on a small ledge 2/3's the way up, you pull a mo...[more]   Browse More Classics in California

The Riverside Quarry offers superb climbing on steep, featured granite. Unlike other regional areas, the routes here are long, many of them over 100 feet in length. Not only will you find sport climbing, but a handful of excellent quality crack and aid climbs as well. All of this on a cliff that’s centrally located to all of Southern California, and with one of the shortest approaches around.

I visited this place for the first time last week. I want to thank whoever took the time to clean up the area at the base of the shield. The benches, rock and 4x4 retaining walls are wonderful. They make the area seem very nice in contrast to the rest of the quarry. If the climbers who did that ever need en extra guy to help out, i would be more than happy to pitch in. Thanks again for taking the time to clean up this wonderful spot.

You can thank Louie Anderson (socalbolter) for the drive and vision to make the Quarry what it is today. There are clean-ups/maintenance days now and then, so keep your ear to the ground.

Riverside Quarry; developed by Mark Smith and Richard Jensen. And a few others. Late 70's early 80's.

An amazing area! It offers so many quality routes from easy moderate to fairly difficult. It's proximity to L.A. and warm winter sun offer a great day trip destination and a sweet alternative to Joshua Tree. Every route I have been on is quality and worth repeating. I've noticed the Quarry holds a stunning similarity to Rifle. It climbs almost exactly the same... just no polish and nothing is drastically steep.

More break ins. Today 2/28/10 a white suv was broken into with evidence that there was another break in but the car was gone already. It appears as the person stole their gps unit. Just another reminder to be careful not to leave anything of value insight or in your car period.

EDIT: A man-made break that claimed Redrum and The Sweetest Thing at the beginning of March. If you read my original post, rest assured this was intentional; apparently the rock had shown visible signs of movement so they took it down before anything bad happened. Thanks to Louie and everyone else who helps keep up the quarry.

This rock "fall" was intentionally done. That section of detached rock has been progressively shifting over the last few months. I and others had become aware of this and steps were taken to remove the rock at a time when no one was around.

The quarry as a whole is a work in progress and as loose rock is discovered it is either reinforced or removed. Sometimes (as in this case) routes are lost as a result. Rest assured that we will be cleaning and bolting the newly exposed rock, so there will be new routes on much more solid rock as a result.

In a continuing effort to make the routes at the Quarry as safe and solid as possible, I have removed many tons of expanding and loose flakes off the flake band in the middle of the routes Culture Shock, Choss Revolution, and Buzzkill.

Over the next week or so, I will clean the newly exposed rock further, replace and/or move bolts and move on to the next on a long list of "to do" items at the Quarry.

Please enjoy other routes while this work is being done.

Thank you,

- Louie

Thanks for cleaning that choss around Choss Revolution Louie. I've been wanting to climb that route, but last time I was there some climbers were breaking off huge pieces of rocks on that route (I'm sure it was accidently and also purposeful on the obvious loose rocks). It felt to choss to climb seeing rock fleeing down to unexpected climbers. Thanks again for keeping it safe out there.

So the story takes a turn for the worse:

I was out there yesterday until about 2:00 pm. I left a static rope clove hitched to a few random bolts here and there in the middle of the affected routes, having brushed all the dirt off the exposed rock. I wanted to be able to just jug up and do the remaining work.

Returned this morning at 8:00 am to find that someone had stolen the rope and 6 or 7 draws.

The Quarry was crawling with people yesterday in this area, so someone either did this with everyone watching, or stayed around until the crag was empty and did their deed.

I did some crappy things when I was younger, so maybe this is just my dose of karma, but it really sucks to have things like this happen. Since development of the Quarry began, I've lost about a dozen ropes and untold numbers of draws and biners.

If anyone saw anything, I'd appreciate hearing about it (although I'm not expecting much...).

PSA to my fellow climbers: break-ins at the Quarry are still a problem!

Someone smashed the back window of my Jeep yesterday (2/5/2014) while I was parked on Sierra. The thief (thieves) was clearly not a climber as he didn't touch my camera, rope or trad rack, and instead made a beeline for the local car stereo shop and some ghetto jewelry store in Fontana to try and make purchases with my debit card.

I will be parking well back in the neighborhood from here on out as an extra five-minute walk is well worth not fixing another car window for $230. Here's hoping others can learn and benefit from my bad experience...

Arrived at the quarry today (8/2) and as we walked up, the sheriff was pulling into the quarry. We flagged him down and asked about the fence...he said the fence is to prevent the off road vehicles from coming in. He said climbers are still allowed but just don't park inside the fence.

Nearly every time I come here I find a belay tag from either Sender One, Mesa Rim or some other ritzy gym. You may have just learned how to clean routes but please learn to clean up after yourselves before trashing the crag.

When we left the quarry today we saw a black and tan Chihuahua running around the neighborhood. We grabbed her so she didn't get hit and took her to get scanned for a chip. No microchip, no collar. She looked really well cared for so we took her to the Riverside county shelter. If she was yours, check the shelter.

Hello all. My partner and I had to abandon gear on the 5.9 on Slab City Right because I fell and got a head injury, and we had to make a quick exit. If anyone is able to grab the gear I would be immensely greatful. Please send me a PM if you do and I'll get in touch with you.

All the best,
