Camp host was extremely friendly and helpful. The site by the stream was incredibly beautiful. We loved it there.

This was our second stay at Diamond O campground (last time was 10 years ago). The campground was very clean from the campsite to the restrooms. The hosts were friendly and checked in with us periodically. We will be returning again, hopefully sooner this time.

Amazing campsite and hosts! The park entrance to Yosemite was closed because of the weather so it was a far drive to the open entrance (3.hrs). There were so many places and hikes to explore nearby the campground. They were just as amazing as Yosemite Valley. The host Jenny provided my boyfriend and I a tent because we had forgot our tent poles. The bathrooms were very clean as well as the sites and the river was very close by. I will definitely be back!

Beautiful campground. The road in is rough, but sites are well maintained. Pit toilets, bear boxes, fire pits, tables, tent pads and driveways were all top notch.

Love this remote camping area, scenic quiet and just plain beautiful. The road coming in is a little rough and narrow in spots, but we had no problems with the 31" RV. We also had family camping with us in a 36" RV with no issues on the road. Lots of local hiking trails and Hetch Hetchy is a must see. The falls this year are spectacular. Walking sticks highly recommend for Hetch Hetchy. Yosemite Valley is about a 30 minute drive (when the road reopens). The small town of Groveland is place to hit...make sure you check out the ice cream store (the Grove Mercantile) and I hear that Two Guys Pizza Pies is fantastic.

Great campground. The campground owners' generator was a bit loud at night/in the morning, but we were far enough away that it wasn't too big of a problem - would hate to be in the sites right next to them though!

Wish there was a place to wash dishes, but I get that it's sort of a "semi-backcountry" experience so they only have water spigots and you have to wash your own dishes elsewhere.

Visit Hetch Hetchy while you're there, even if you just drive up and walk the dam, it's worth checking out! The campground is so close to it, would be a shame if you missed it.

Best place to stay when you go to Yosemite. All other campgrounds are booked out and you'll be sitting right next to each other. Diamond O is great because you won't have any noises and it's very quiet and relaxing.
When you can book online pick the spots away from main entrance and you'll love it!!

Great location for visiting Yosemite including the Valley, Tioga Road, and Hetch-Hetchy. Nice, small campground with some spacious sites. Most campers were quiet and respectful of fellow campers. Only about 1/2 full during our entire stay. No cell service but hey, you're camping!
