Went here on the weekend of the eclipse and it was very full, but we still found a good spot with great views. I’ve been here other times in the past and it’s usually completely empty. The road is a little bumpy in places, but I’ve seen tons of campers, RVs, sedans and other low clearance cars make it just fine. It was in the 70s during the day and 30s at night. It takes a while to warm up in the morning because the mountains block out the sun until around 9 or 10am in the fall. The sand is very fine and everything you bring will end up with a layer of dust on it
