What Guests Are Saying

Dimond O Campground offers spacious, clean sites nestled among trees, providing a peaceful atmosphere with ample amenities like clean bathrooms and friendly hosts. Many reviews highlight proximity to Yosemite, beautiful scenery, and a nearby creek for recreation. However, there are some concerns about limited potable water, occasional unpleasant odors, and noise from generators; overall, visitors often express a desire to return.

This campground is absolutely great. Very clean and well maintained. There is a trail to the nearby river that makes for a lovely walk. I very highly recommend this as an alternative to campgrounds closer to Yosemite that might be full.

We have stayed at this beautiful campground since our, now adult children, were little. It had been a few years since we were back but we love DimondO and returned for my wife's 60th birthday with our kids traveling with their spouses. The area is wonderful and well placed for day trip adventures. In the past there was a regional camp supervisor as well as camp host at DimondO but this year only a host, who in my opinion need some supervision. As we rolled in at 1:30 pm and were exploring what campsites might be available (we didn't get our first choice in online booking) we approached the host as he was finishing cleaning a site. He was rude and commented that it was still "first thing in the morning" and we were obviously bothering him. Later that evening, selling fire wood, his deminer was completely different, jovial and slurring his words, apparently he just needed some "medication" to turn his day around. I will return to DimondO but hope that the folks who choose camp hosts do a better screening job next time.

The atmosphere is very quiet, except when you're camped near the hosts which means you have to listen to their loud generator from morning til 930pm..

Booked one night before a backpacking trip in the Hetch Hetchy area of Yosemite. Arrived late at night (like midnight), set up my tent, and left at 8:30am the next morning. Campsite had a nice raised sand/dirt pad for the tents but be careful not to fall off the pad if you set up multiple tents on that raised pad. Bear locked was great and the bathrooms were fine. Didn't have a chance to use the fire ring or explore the nearby river. I'd be happy to stay at the Dimond O again!

The campsite and grounds were clean. Water was provided at each campsite to put out barrel camp fires. The restrooms were cleaned each day. The camp hosts drove to each campsite to ask if fire wood was needed. They also drove around each morning to check on each campsite and to answer any questions.
