Nice Campground. LOTS of noise.
I stayed here for 3 nights on 4th of July weekend. I really liked the campground location and layout but I was pretty disappointed with the level of noise throughout the night. It seems to be the standard at most of the popular national park campgrounds. It's just what happens when you have over 100 campsites in a relatively small area. That being said, hearing a car alarm going off over and over can really take away from your wilderness experience. We stayed at sites 132 & 133 with a group of 12 people and had plenty of room for our group. We were right next to the bathroom which was nice when you had to go, but not so nice when you can hear people walking through your camp all night going to use the bathroom. Bathrooms were pretty clean and had flushing toilets.
Good location. Close to visitor's center and General Grant tree trail. It is also a good central location if you are interested in seeing Cedar Grove and Lodgepole areas. You are about 1 hr from each at this campground. Azalea campground is very close by and appears to be similar to this one.
Overall, I usually go to the National Parks to enjoy the sights, trails, & back country, not my campsite. My experience in the park was still great even though I didn't really care for the campground. I felt lucky to have a campsite within the park close enough to all of the attractions and amenities. If total piece and serenity is what you are looking for, look into back country camping.
