I have now been to Norris Hot Springs two years in a row on the last weekend in September. I love the small number of camping spaces and the rules that all campers actually follow (no loose dogs, no generators). The camp bathroom/showers are super helpful and it is awesome to just walk across the parking lot to the spring.

The food is amazing and the staff are all super friendly. Both years I've been, it has snowed either a dusting or an inch-ish. The camp spots do not become a muddy mess and the drive is still easy to navigate on foot or by small vehicle. 

We might make an annual trip here if we can budget in the time off. It is the perfect spot to setup camp and then go explore the area.
