We stayed 6 nights in a 40' 5th wheel. This is about as close as you can get to Yosemite without being inside the park. The weather was great and the RV part of the campground was moderately full. The sites are fairly level but the whole park is built on a mountain so everything is on an incline. Even though the RV App said the unit was level, we could tell it was just a bubble off. It didn't bother me. The sites are gravel with a picnic table and fire pit. No fires allowed while we were there due to fire danger. The bathrooms are a bit dated but they were clean. They have a store that carries a few items but if you need groceries, you will have to go to Groveland, about 3 miles. The park has a lot of other non RV camping facilities they rent like cabins, Yurts, Chuck Wagons, Vintage RVs, etc. They have a pool, a deli, and laundry facilities.
I would give anyone a recommendation to stay here as it is a clean, well managed park and they staff was friendly. It is a bit tight for big rigs, but it isn't the worst I've been in. We would definitely stay here again.
