Very nice campground. There were flies and mosquitoes present during the evening hours but nothing that cant be handled by insect repellent. Area is great, there is a river close by with pools, Yosemite entrance and visitor center is close by, and many trails to check out. Will return to this site.

Very nice and neat campground fairly close to Yosemite Park. Clean bathrooms, spacious campsites with leveled space for tents, fire ring, table and bear box.
There is a river close by.
The only thing is that the forest is burned here but it is not about the campground itself.

The site pads were very level. The campground host, Robert, was exceptionally kind and helpful! The bathrooms were clean and regularly stocked. The walk on the trail to the river was awesome. The only down side are the large piles of downed, dead wood surrounding all the campsites, distracting from the view. On the other hand, with the fires, we are lucky there still is a campground close to Hetch Hetchy.
