I was three days early- the campground would not open for three more days! But I was able to talk with a fellow that works at the store just outside the campground to get some info. The campground is used by lots of thru hikers on the Pacific Crest Trail as well as the John Muir Trail (I saw a large group of thru hikers filling up on food from the the store and grill on picnic tables outside) as well as campers who wanted to enjoy the high Sierra area of Yosemite Park instead of hanging out in the crowded Valley. The campground is huge with around 300 sites that accommodate tents, RV’s, Camper’s, and even a few equestrian sites. I was told that the sites in the A loop are the best sites since they are a bit more spread out, are near the river, and the backpacker’s area is there and that is where you get the best stories. Across the road is the Tuolomne Meadows area with great hiking and access to the big trails. There was a really neat soda spring you could hike to where ice cold water bubbled out of the ground. There were some historical buildings in the area that were pretty neat to check out as well.
