Wawona is a great choice!
We camped in mid-April and had both a bit of snow and springtime weather. The campground is spacious and pull through campsite clean, pretty level, and right along the river. Wawona has an interesting historical area and a not to miss waterfall that is a nice hike and just lovely. Because it is set back, there aren’t the crowds as in the village. Wawona is a nice drive away from the Village and other must visit sites.
