Sweetwater Creek Campground is almost right across the street up Highway 120 less than half a mile
Pine Mountain Lake community in Groveland has a campground. It's located 30 min away from Yosemite North entrance ( Big Oak Flat entrance station). I think it's $27/night.
Yosemite Pines is one. 20-30 minutes max. Has everything you need. Showers. Bathrooms.
Yes but I don't remember the name
