The campsite was cozy but you have to pay $2 in quarters for a "18min" shower which was more like 10mins. There was quite a bit of trash around the site. We picked up and threw away what we could. We camped there on a Monday then backpacked in the grand canyon and came back to Mather on thursday. Not very quite but great if you're wanting a cheap in the park option for sleeping.
The bathrooms and camping grounds were clean and tidy. I usually find trash on the ground but our site here was trash free. The hiking trails are wonderful. Saw wild turkey and a fox. I reccomend going in spring. Not too hot and flowers are in bloom. This was our first stop on our roadtrip from Dallas to the grand canyon. We plan to return with friends.
