The sound of cowbells echoing through the night signals the rural character that defines Dimond O Campground, where cattle occasionally wander near campsites in this working landscape. Located three miles down an access road from Highway 120, this Forest Service campground sits along a creek that provides swimming holes and the constant background murmur of flowing water.
Reviewers consistently praise the facility's upkeep, with "clean bathrooms, clean grounds" maintained by attentive camp hosts who sell firewood and keep the pit toilets surprisingly fresh. Many sites back directly to the creek, while others require only a short walk via footpaths to reach the water. The spacious sites offer privacy between neighbors, though Megan K. notes that "site #28 is actually one of the best because it is really secluded."
Fire damage from past blazes has left some areas with weakened trees, and campers report hearing occasional tree falls during windy conditions, though dangerous trees within the campground itself have been removed. Cell service is nonexistent throughout the area, requiring advance planning for communication needs. The campground fills regularly, particularly on weekends, with both reserved and first-come sites available.
Access requires navigating the three-mile campground road, and the location serves many visitors as a staging area for Yosemite National Park, positioned about 15 minutes from park entrances. Early risers can reach Yosemite Valley by 7:30 AM to secure parking before crowds arrive. The proximity to Hetch Hetchy, just three miles away, makes this a convenient base for exploring the less-visited northern section of Yosemite.
For those seeking developed amenities closer to town, Hodgdon Meadow Campground — Yosemite National Park provides an alternative with more services.
