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 Tacos - for all your pre/post send calories 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 (socalbolter@cox.net) 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.

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. Jun 4, 2008

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. Dec 29, 2009

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. Feb 28, 2010

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. Mar 3, 2010

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. Mar 6, 2010

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,

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...).

The new guide is really good. Well laid out and full of the usual info you want. It also has plenty of color pictures which really make you want to get out and climb at the quarry. Jan 31, 2012

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... Feb 6, 2014

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. Aug 2, 2014

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. Nov 30, 2016

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. Dec 27, 2016

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,

I went excitedly to the base of Utopia yesterday, looking forward to repeating my favorite climb at the Quarry, but I couldn't find it. After staring confused at the wall, I realized that what once was a left-facing corner, there was now only a blank face. A giant pile of boulders layer beneath it.

Anybody know when this rock fall happened?
Did it happen a while ago and I'm just behind the times? Apr 2, 2017

More rockfall sometime this week I believe? Or did someone trundle it for the purpose of safety? ..very large chunk fell off Minimizer/Maximizer, Nemesis, Wonderstuff in Torture Machine area. Debris all the way down the hill. A large rock even made its way to the base of the hill at the start of the steps. Bomber. Hope nobody was in the area when it happened. Feb 10, 2018

What would people suggest climbing that tends to be more solid? Aug 9, 2018
There has been a ton of rock fall this past year. The entire dihedral of wonderstuff is now gone. There’s also a massive chunk of rock with 3 bolts on it that has also broken off near whammy. Not sure what route this is but it’s pretty gnarly to say the least. Was out there this morning and a rock the size of a cooler came off the top. Please be careful out there. Many bolts are placed in poor quality rock that appear ok but in reality are placed in a fractured sheet of granite. I know we take risks as climbers but keep in mind the seriousness of risks associated with this area and wear a helmet. Nov 22, 2018
I felt that the left side of the tall walls (metro, left of the roof, and roof) seemed pretty solid. Sure there are holds to cooler-sized blocks with x's on them, but not really more so than all but the most-used crags.

I'm really growing to love climbing at the quarry and would love to take part in cleaning off some of the bad rock. I'm not experienced in this area, but would love to donate labor and/or money for equipment to help with the effort. Nov 29, 2018

"What would people suggest climbing that tends to be more solid?"

Try Joshua Tree! The Quarry is a quarry, and with all the fracturing it is and always will be loose. Cleaning and engineering can help, but rock fall is a certainty.

Personally, I stopped climbing there when a basketball sized block almost took out me and my partner. It isn't safe, and I wouldn't encourage anyone to climb there. Sure the climbs are fun (gym climbing outside), but is it worth the risk? There are better and safer places to climb. Nov 30, 2018

  • Take/Hide Your Valuables, car break-ins are still a problem*

The Saturday before Christmas, my friend drove and we spent 3-4 hours in the afternoon near the Roof area. She had left her Wallet and Phone in the back area (hatchback) and when we got back the back window was smashed and those 2 items were taken. Windows were tinted but not limo dark, so you can't see it via casual inspection but from the right angle it might have been possible to see. Nothing else was taken(cams, jacket/shorts, shoes in a box, items in glove box).

One mistake was parking it on Sierra Ave east/north side next to the short wall which is not next to the houses, and also the wall prevented the car from being seen from the wall. If parked in the housing area, probably would have been safer. The thieves tried to get gas with every single card in the wallet within the hour. Unluckily for them, the zip code on the license did not match the cards except for 1 card which had no balance on it. I'd recommend calling all the card companies immediately as she did to avoid any $ hassles.

So take your valuables with you, but that's always the advice. On a more remote trailhead if I didn't want to carry valuables I'd probably hide it in the bushes not far from the car. Jan 9, 2019

to climbers-- there are at least two pairs of nesting red-tailed hawks and one pair of nesting ravens on the face! please please be wary of them.
some friendly reminders...
red-taied hawks may sometimes attack when their nests are threatened, which includes using poop or throwing animal carcasses on anyone below their nest. they nest only for about three months at a time, then move on. if you are noticing some unhappy birds near where you are climbing, please be aware of your surroundings and pick routes that leave them some space. hawks are federally protected by the Migratory Bird Treaty Act. Removing or destroying them or their eggs is a federal crime. Jan 29, 2019 · Temporary Report

PSA: I was out here in the afternoon on 2/19, wrapping up just before sunset and my girlfriend and I had an unsavory/aggressive interaction with some of the locals- chucking sandbags off the cliff right above us, acting aggressive, yelling at us to "get the f**k out of our territory"... My best guess is that they had some affiliation with the spray-painting crews that seem to be around there after hours.
Just a heads up to all climbing out there: I'd make sure to be aware of who else is at the cliff (we were the last climbers there) and to try to get out of there earlier in the day. 1 day ago
