Stayed here on a Saturday a week before Christmas. Was amazed at what a ghost town the area had turned into. Drove thru the Park back in October and it was absolutely packed...every turnout full, every parking lot full, etc. This time it was just the opposite...empty lots everywhere you looked, and all the shuttle buses parked for the winter The campground is shut down so that only one loop is open in winter. We got there mid-afternoon and had no trouble getting a spot, but it looked to be full or close to it by nightfall. Spots are fairly close together and what few trees/shrubs there are have lost their leaves, so you won't feel alone. Crisp.cold morning in the low teens, sunny with high around 30 in the afternoon. Went on three nice hikes, including Angel's Landing. If you want to avoid the crowds, a sunny winter visit is the way to go!
