Dimond O

While it involves a slight detour down a secondary road off of Route 120, Diamond O is a true gem of a campground (pun intended). During my first night in the Yosemite area I camped in Hodgdon Meadows just inside the park boundaries. This forest service campground is much nicer than anything in the park, believe it or not. At this campground you'll get an actual framed, level pad for your tent, designated parking for your site (neither of which are present in the Yosemite CGs) and a very nice fire ring setup with a grill and rods for hanging cooking pots. Unlike some forest service campgrounds it also has a host. No flushing toilets, but I'd take the tradeoff for the other features. AS A BIG PLUS it also has plenty of walk in sites, many of which were open even on a Friday night in July. Don't change a thing, Diamond O.

The campground was quiet and friendly. Platforms for the tents were a step up (about a foot), but totally necessary for snow and rain. One slight complaint - we looked for recycling containers but didn't find any. Otherwise, it was a great launching spot for a day at Hetch Hetchy Reservoir and a hike up to Wapama Falls. Unfortunately, we didn't have the equipment in July 2023 to cross the Tueeulala Falls (sturdy hiking sticks and good first aid kit in case of a fall), so we turned back and will have to go back the next time the falls are in full flight.

Gorgeous site! Close to the creek, full of trees but not too dark or cold, spacious and in good shape. Close to the Yosemite Park entrance.

The Camp Manager was very pleasant and informative to talk to and the restrooms were kept in the best shape I've seen in my 40+ plus years of camping @ Dimond O! Kudos to all involved!

Love this place. We come up once a year to get away from the city. Family friendly, Campground host are friendly and keeps the area clean and safe. Nice camping pad with picnic table, and fire pit.

Stayed at Dimond O few times already and very happy about it. Camping is well maintained and clean, close to Yosemite and Hetch Hetchy. Depending on season be prepared for some mosquito.

The campsite is nice and close to the bathroom and water spout. The issue was the miscommunication from the camp hosts. I reserved this site for friday and for the weekend. The site was first come first serve(on recreation.gov) for saturday so I just paid for the site then so there would be no issues. Saturday morning the camp managers came to my site and didn't even say good morning before they started being rude about me paying for the fcfs site. They said I couldn't do that and this isn't a fcfs site (which I even screenshot the days for proof to be prepared for anything) when it fact it was, they were assuming I was going to cause a problem because I didn't reserve it online when I was trying to tell them it was first come first serve online which is why I Only reserved the friday spot even though I planned for the weekend. The lady then went on to tell me I can't reserve anything without checking with her first but the pay station clearly does not state that on the rules fir paying. I found it really weird how we were the only fcfs site they came to and scolded when we did nothing wrong. They ended the interaction with "well luckily for you the site was available anyway" which I already knew because it was fcfs? lol I think camp managers should have a hotspot to have access to recreation.gov to prevent unnecessary conversations like the one I had. I even had a neighbor tell me it was weird how they approached me. Hopefully their communication gets better for future campers but unfortunately it for me it didn't feel good to be scolded for literally nothing because I ended up being right.

We loved that there were enough first come first serve campsites that we could actually get a campsite. Beautiful campground, nice hosts.

My spot was clean and ready to go. Loved the free access to water

Great location, nice river 50 yds away, and good facilities.
