Every time I go to Yosemite, I stay at Diamond O. All of the camphosts through the years have been amazing. This is north of Yosemite Valley. Away from the hustle. It's got a great river/creek going through it and several smaller waterfalls and swimming holes nearby. Clean bathrooms, clean grounds. You will want to keep your eye out for wildlife. I even woke one morning to cows in our campsite!
Campsite doesn’t have the most beautiful views of trees and mountains as other nearby Yosemite campgrounds but the nearby pools from the stream provides shade and a refreshing dip.
