Good enough for visiting Yosemite
I booked this campsite because it was the closest I could get to the valley. At least it's within the park! The campsite itself has everything you need - all the basics. However there is little stuff between you and the family next to you. My friend and I were next to a large noisy family and that was kind of annoying, but with earplugs I slept just fine.
If you can book ahead enough, really try to get a site in the valley. The traffic in the park is horrendous. Entering and leaving the valley area is such a nightmare. It would have been splendid if we could've just stayed there.
