San Onofre State Beach San Mateo Comments & Reviews
Visited San Onofre State Beach San Mateo Campground lately? We'd love to hear about your adventure. Did you find us useful? Did we forget something? Anything our community should know before heading out to San Onofre State Beach San Mateo?
I’ve made a reservation for site #003 but there’s no photo. Oversight or should I be scared? San Onofre doesn’t get the best reviews…
Had a great experience! Camped here in April, everything was green. It was quiet and peaceful. I say it was quiet but hubby and I were debating if the sounds we kept hearing were woodpeckers or machine guns from Camp Pendleton School of Infantry, either way loved the sounds. We had site SM037 which had beautiful views.
My wife and I would be interested in spending time with our daughter, husband and new baby girl in San Clemente. We would like to drive our travel trailer there and stay from early January to mid February, 2021. The travel trailer is 17 feet with no slideouts. We have two small dogs under 25 pounds. We would require 30 amp service and water and sewer. Could you email me a price for that length stay, please. We are 71 and 73 years of age and Good Sam members.
Congratulations on your new granddaughter! San Onofre State Beach San Mateo campgrounds charges $20 per night for electric hookup sites. You can stay up to 7 consecutive nights. You can click on the ‘Make A Reservation’ button to check availability, pricing and make a reservation. Reservations are accepted on a 6-month rolling window, which means that you can try and make a reservation exactly 6 months to the day of you want to arrive. For example, if you want to begin your stay on January 1, then the first day reservations are open for that arrival date is on July 1 at 8:00AM Pacific time.
Are RV’s allowed in the tent primitive spots?
Hi Melissa, I’m not familiar with any tent primitive campsites at San Mateo Campground (San Onofre State Beach). All of the 145 single-family campsites can a accommodate a trailer or RV.
Can an RV and tent both stay on the same site in the San Mateo Camp, specifically #SM08. Not able to find this info on the site.
Yes, you can have an RV and also pitch a tent a San Mateo campsite #8, as well as other sites.
Just want to confirm Site 02 , 03 can have a tear drop trailer along with a tent . We are going to have a tent per site.
Yes your towing vehicle and tear-drop trailer will fit in campsites 2 and 3. You can also have a tent in each campsite, although site #3 looks to have a tent pad area on the smaller side.
On some websites, San Onofre State Beach /San Mateo campground appears to have dispersed camping nearby. I could not find any additional info on this and since all the regular campsite seems to have been fully booked for Aug 7-9, I wonder if this could be an option since I am fully equipped for boondocking. Is it allowed? Any help with this will be appreciated.
We are very familiar with San Onofre State Beach (Bluffs and San Mateo campgrounds) and we’re not familiar with any dispersed camping outside of the campgrounds in the area. Both campgrounds are surrounded by Camp Pendleton Marine base, so no sure where the dispersed camping might be location.
Hi – I see that there is a 3 vehicle limit per site, if they fit. I recently reserved SM046 which says it can accomodate a 36 ft trailer. If a partner and myself have 2 small trailers, is this allowed? Their combined length would be under 36 feet. Thanks.
Good question Evan. San Mateo campsite #46 is pretty long and if there is a maximum 3-vehicle limit, then you should be able to fit one vehicle and two trailers, provided they all fit (and all wheels are on the paved parking surface). The camp host/ranger will make the ultimate call though. It’s difficult to get a live body to pick up the phone, but you may try calling the campground to confirm at: 949-492-4872.
I was wondering about the trail from the campground to the beach. Is the trail very challenging? Is it safe to do with a family? I am from the city and there are trails I would not take my family due to concerns about sketchy people.
The trail from San Mateo Campground to the beach is about 1.5 miles and mostly flat. It has a little hill along the way, but not bad. Also the trail is well maintained, heavily traveled and safe. Chances are slim you’ll see a hobo or sketchy person.
We are going to arrive after 10 pm Friday night 9/25. Will that be OK and can we access our reserved campsite?
Yes – you’ll be able to access the campground and get your reserved campsite arriving after 10pm Friday night (if that is the first night of your stay). You have up until 7am the next morning to claim your site.
Can we have 3 vehicles parked at a site? also is there a parking lot for additional parking?
At San Onofre State Beach – San Mateo Campground – you can have up to 2 vehicles in the RV hookups sites (1-67) and all others campsites can accommodate 3 vehicles (extra charge for a 3rd). The maximum occupancy is 8 people per campsite. There is also an overflow parking area at the campground.
We are driving from Colorado to San Mateo in May 2021 to welcome our grandchild. We will be staying a month. Is there an area that has better wifi than others ? We’ll be in a 34′ class A RV. Also I’m confused on the 6 month window to reserve. Is it an exact calendar month or mathematically 180 days?
Congratulations on your expected grandchild – very exciting! San Mateo campground does not have internet/wifi service, but the cell phone reception is good there (for wifi hotspots). Also, keep in mind that campers are limited to stays of 7 consecutive nights at the campground.
You can have up to 2 vehicles in the RV hookups sites (1-67) and all others can accommodate 3 vehicles (extra charge for a 3rd). The maximum occupancy is 8 people per campsite. There is also an overflow parking area at the campground.
The websites have conflicting information. There is no fire advisory on the main website or fire notices, but the site booking under amenities “campfires not allowed”. I have tried to call and no answer. Voicemail says its full. Are propane fires allowed?
We are not aware of any fire restrictions at San Onofre State Beach San Mateo. With that said, if the area experiences strong winds, they may go to a stage 1 (no campfires or propane fires). Perhaps a recent camper can comment here as to if campfires are currently allowed.
Hi there! We have stayed at San Mateo many times before, but recently upgraded to a 35ft 5th wheel. Can we still stay in the tent sites? We’re specifically looking at #S150. Thanks!
San Onofre State Beach San Mateo campsite #S150 has a pad length of 36 feet and there is also some overhand off the back. You should be able to fit your 35ft 5th-wheel and the towing vehicle (parallel park) in that site. Have fun!
Is the San Onofre San Mateo campsite open for overnight RV camping? I have a reservation coming up, but according to the reserve California website, the campground is closed. Please clarify.
Good of you to double check. The California State Park page has not been updated since Dec 7 on ‘closure announcement’. I do know that most of the California State Park campgrounds have recently reopened. However, we are not located at San Mateo campground so can’t say for sure. They are taking reservations though for this week at San Mateo (ReserveCalifornia) so I’d say it is open. You probably should try calling the park/campground just to make sure: 949-492-4872.
Quick question. I’ve booked site 111 in August. I’m planning to tent camp. Is this allowed at this particular site? I could not tell if the picture of the RV on the map only means RVs only? Or you can tent camp too? I’ve tried to call the campground but haven’t had luck getting in touch with anyone there.
Thank you for any insight.
Yes you can tent camp in San Mateo Campsite #111. Have fun!
We booked the hook up site #67, but planning to use tent only… Are hook up sites allowing tents only?
Yes, if there is room in your campsite area.
Are hook-up sites allowing tents only?
Yes, if there is room in your campsite area.
We have used both #138 & #135 recently, and both sites are recommended. Flush toilets & pay showers.
We reserved #69. It looks like its next to a trash can. Is being next to a trash can problematic at all?
It should not be a big issue. Your camping area is a little distance from the trash can so there should not be any smell. You might hear the lid close from time to time (campers depositing trash), but usually not at night.
Are RV’s allowed in tent sites? We have sites 122, 123, and 125. Thank you
Yes – you can have an RV parked at campsites 122, 123 and 125 at San Mateo Campground.
Hello, I am camping at SM081 in a couple weeks. My reservation says that the spot fits 3 cars and 8 people, but that the tent pad spot is 10 x 10. Do these camp sites allow more than one tent?
Also it says the spot has a fire ring, but then it says fires are not allowed. Does anyone know if these spots allow fires? Thanks!
Yes – you can put up more than one tent, if there is room in the camping area. They usually allow fires there, but the past few days had a ‘Santa Ana Window Condition’, and they probably shut down fires during the period. It’s going to be a dry summer so not sure what they policy will be regarding fires. I’m sure they won’t be permitted during windy conditions.
Hey. Are generators allowed in primitive camping areas? Normal daylight hours of course. Thanks
You can use generators at San Mateo campground during daylight hours.
You can use generators at San Mateo campground during daylight hours (10am to 8pm).
We reserved SM118 and SM119 for June. Just wanted to check:
1) Does the campsite have a BBQ Grill?
2) Are we allowed to do campfire in the provided fire pit?
The campsites don’t have a BBQ pedestal/grill, but there is a grill/grate that folds over the fire pit. You can have fires in the campsite fire pits, unless there is an extreme fire-hazard (strong winds). Weather/winds should be okay in June, but Park Ranger / Camp Host will let you know when you check in. Have a great time!
Wonderful. Thanks for the quick response
I booked San Mateo Sites SM 051 and SM 065. Do you require an RV in those spots or are tents only acceptable?
You don’t have to have an RV in those campsites. You can also tent camp as long as the tent(s) are in your camping areas.
We have site SM016 this week…the 5th wheel is 40 feet. Pad length is 36 but site length is 50. As long as we park the towing vehicle in overflow, would that be ok?
That will work – parking your towing vehicle in overflow.
I made a reservation for an RV spot SM063. My RV is 38′ but looks like these spots only allow 36’… is this correct?
As long as all wheels are on the paved parking surface and the front end is out of the campground road you’ll be okay. Campsite #63 has an overhang area off the back so you should be able to back up your RV to where the wheels hit the curb.
Are all of the campsites a mile walk from the beach or are there some that are closer?
They are all about a mile from the beach – ranging from a mile to 1 1/2 miles. There is a trail from the campground to the beach.
Hello, I made a reservation under my account for myself and I invited my brother to join me.
My brother is planning to arrive at 2pm but I cannot get there until 4pm. Can he check in without me ? Or do I need to be present since the reservation is under my account ?
Your brother can check in before you arrive. He’ll need to know your name, site # and your reservation number. Have fun!
I would like to see availabilty for san mateo campground for 2 nights. I’ve tried calling the number provided and mail box is full.
You can click on the ‘Make A Reservation’ button to check availability, pricing and make a reservation at San Onofre State Beach San Mateo campground. You can also call the reservation number at 800-444-7275.
I’m looking to Reserve a space for RV camping but it says administrative is that open to the public to reserve online if it shows available
Hi, I hope this is ok to ask here. Are we allowed use a tow truck to transport an RV into a reserved RV site at San Mateo Campground at San Onofre SB? The tow truck will unload and leave on the day of check in and return to pick it up on the day scheduled to check out? Thank you.
I don’t know of any policy/rules that say using a tow truck is not allowed. You may try calling the park/campground to confirm though: 949 492-4872
I have a reservation for 10/26/21 at San Onofre/San Mateo Campground for “Group Camp 1”. Where exactly is that located in the campground and does it have any water or electricity?
The group camping area at San Mateo campground is over by campsites 141-145.
Is there a paved bike trail around the campsites and to the beach?
The trail (Panhe Natural Trail – Trestles Beach Trail) from San Mateo Campground to Trestles Beach/San Mateo Point is about 1.5 miles. It is dirt/gravel for the first mile and then paved for the last 1/2 mile to the beach.
What is the coin operated shower info please. Quarters? Time allowed?
The showers at San Mateo campground are indoors and have hot water. They operate on tokens, which you can purchase from a machine at the campground. Not sure what the rate is, but usually it’s about $1 for 3-4 minutes.
I have a group camping at San Mateo campgrounds next weekend and cannot find a confirmation of the max length of RV for sites 80, 83, 85, & 86. Is the max 25 or 36?
Hi there! I reserved the group campsite in June, but was thinking about getting a couple regular sites for those folks with trailers/RVs. I see that the sites with hook-ups are already booked, but wondering if you can recommend any other good sites for trailers/RVs or close to the group site? Thanks so much!
Good job on reserving the group campsite! We have a few favorite (non hookup sites) over in the loop near the group area. Those include 142, 145, 148 and 150. Hopefully you can reserve 1-2 of those.
Ya, I was pumped we were able to snag it! I’ve camped at San Mateo a couple times but never the group site… is it a good one? And darn, looks like just 146, 152, 155, and 157 are available. Any faves of those?
You guys are so awesome, can’t even tell you how much I use this site (and actually just signed up for the ‘Campsite Assist’ for San Clemente group)! Keep up the good work.
Right on – thank you very much for the kind words and support. We love providing the photos and other camping services for sure. Hope you score that San Clemente group site.
As for those other San Mateo sites – they are all pretty good. I think #146 is pretty private, but not a room of tent space. Sites 155 and 157 would be nice too – especially if you’re looking for both – as they are right next to each other.
Hi again! I see that there is an overflow parking lot, but was wondering if you know if this is day use only or can people leave their cars there overnight? I was also wondering if you know if there are BBQs/grills in the group campsite and shade structures at all? Sorry for all the questions and thank you! 🙂
San Mateo’s group campsite is for tent camping only and can accommodate up to 40 people and 8 vehicles. Sleeping is not allowed in the vehicles. There is limited shade in the camping area, but there are 2 shade Ramadas and a few trees that help. The group site has 2 fire pits, 1 large BBQ (charcoal or wood), 6 picnic tables and potable water.
Also, overnight parking is not allowed in the day-use parking lot.
Hope this helps!
Yes that is super helpful, thank you so much! Do you know if there is overflow parking other than the day-use lot?
Unfortunately there is not any overnight overflow parking at San Mateo.
This website has answered almost all of my questions! I’ve tried looking on the main site and also calling the campground but I found this campsitephotos.com to have awesome info! Thank you! We’re looking forward to camping at Mateo again. I haven’t been there for almost two decades!
Thank you Emily! Really appreciate your kind comments and glad we’ve been able to help with your camping vacations. Let me know if you have any questions about San Onofre SB / San Mateo. It’s a really nice campground and I think you’ll really like it (again).
Hello, I’m planning on booking a group tent site but where will the vehicles go? Is there an area on the site to park them? (As I noticed it says Tent Only)
The Park Service didn’t have the group area correctly placed on its map for San Mateo campground. We made the adjustment/corrected and you can click on the ‘Campground Map’ button to view. There is a parking area (for about 8-10 vehicles) next to the group tent camping area.
Hi there! I was hoping to find out if tent camping is allowed in site #43? There looks to be more than enough grass. Thank you for your help 🙂
Yes – you can pitch tents at campsite #43. It’s a nice site with good room for tents.
Wonderful!! Thank you very much for your reply. We look forward to tent camping at your campground 🙂
I have book site 101 103 and 132. Which site should be the head quarter for my family to gather for meals etc..
There is really not a whole lot of difference between the three campsites. I’d lean toward 101 or 103.
Hi, we have a comedy show sat night for one of our days. Can we still come back to the campsite after 10pm?
Yes you can!
Hi, I’m hoping to bring my pop up camper (18′ long) and vehicle to San Onofre during a couple nights in mid July. I’m seeing a good number of campsites available (20+) at the Bluff Campground. Where I’m confused is when I put my trailer type, length etc into Reserve California, all of those sites disappear. Are they truly tent only sites or am I missing something here? I’ve tried calling the park directly a bunch of times with no luck. Thanks so much for all your great information on this site. Apologies if this has already been answered.
Good question! You can park a trailer or RV at any of the San Onofre Bluffs campsites – as long as the RV or trailer fits within the parking area. None of the sites are technically ‘tent only’. Not sure why ReserveCA removes the sites once you enter your equipment information. I recommend finding a site you like to reserve (and that has a long enough parking spur) and enter ‘tent’ camping. You can also try calling ReserveCA at: 800-444-7275 to reserve the site that works for you. Hope this helps!
Are campfires currently (June-July 2022) allowed?
Just want to confirm as every website says they are but the State reservation site says no.
Currently camp fires are allowed at San Onofre State Beach San Mateo Campground. They will not allow campfires during extreme fire conditions (usually when it is very windy and dry). Current 10-day weather does not project high winds in the area. You can always try calling the park to check current conditions/restrictions, but many times you won’t get a live person to answer: (949) 492-4872
Do any of the San Mateo camp sites have ocean views?
None of the campsites at San Onofre State Beach San Mateo Campground have ocean views. The Bluffs Campground does have several with some oceans views though.
Heard ants can be a real problem getting into vehicles, tents, food. Is food grade diatomaceous earth or any home spray (apple cider vinegar, soap dish and baking soda) allowed?
Yes, ants can be a bit of a problem at the campground, but not sure of the rules regarding deterrents. Maybe somebody knows and can comment here.
was looking at reserving a site with hook-ups at San Mateo.
do any of the sites have a view of the ocean/beach?
if so, which ones?
San Mateo Campground is about 1.5 miles (via the campground trail) to the ocean. None of the campsites have an ocean/beach view.
These photos are outdated and the campsites are no longer grassy and green. It just a giant dirt campsite now. Very disappointing.
All the photos of the campsites are correct and current. We did take the photos in the spring so the grassy areas were green. With current drought conditions – the grassy areas are no longer green. Hopefully the area will get some rain this winter and green things up!
I booked San Mateo site 15. Site length says 25 ft.
Pad length says 36 ft. What is the difference? Our trailer is 28 ft. and we have a truck tow vehicle. Will both our truck and trailer fit in site 15?
ReserveCA can be a little confusing (and/or inaccurate) with its campsite measurements. In this case San Mateo campsite #15 does have a parking spur (pad) length of about 36 feet. There is also some overhang of a few feet off the back. The park spur/pad width looks to be about 15-16 feet. You’ll be able to park both your trailer and truck tow vehicle in that campsite. I’m not sure what ReserveCalifornia’s “site length of 25 feet” is referring to. Have fun!
