The three-mile access road into Dimond O Campground winds through Stanislaus National Forest, delivering campers to a forested setting where a creek flows directly through the grounds. Sites spread along both sides of the water, with many positioned close enough that the sound of flowing water becomes a constant backdrop. Andrea R. notes the campground "got a great river/creek going through it and several smaller waterfalls and swimming holes nearby."
Camp hosts maintain the grounds consistently well, with pit toilets that reviewers describe as surprisingly clean for a forest service facility. The campground fills regularly during peak season, particularly with visitors staging for Yosemite National Park access. Sites vary considerably in privacy, with some tucked between mature trees while others sit more exposed. Site 28 gets mentioned specifically for its secluded feel. Wildlife encounters happen frequently—campers report waking to find cattle wandering through sites, complete with cowbells echoing through the night.
The creek provides the main recreation draw, offering swimming holes within walking distance of most sites. Fishing opportunities exist along the water, though reviews don't detail species or success rates. No cell service reaches the campground, so visitors should plan accordingly for communication needs. The camp host sells firewood on-site, and the large sites accommodate RVs up to 48 feet.
Access requires navigating that three-mile forest road, which some describe as rough depending on conditions. The campground sits about 15 minutes from Yosemite's entrance gates, making it a popular alternative when park campgrounds fill up. Megan K. found "bathrooms are pit toilets but felt relatively clean" and appreciated the location for early morning Yosemite Valley access.
Campers seeking creek access and a forested setting outside Yosemite's boundaries find this campground delivers both, provided they can handle the access road and don't need cell connectivity.
