It's hard to predict in advance what the weather will be like at that time of year, and I have been camping there in the
Fall for years. As a
very general rule, I have found the deeper you go into October, the greater the likelihood you will
encounter some rainy days and nights, and temperatures also drop the deeper you go into October. Rain is not such an issue
if you have an RV or trailer with a hard roof, more of an issue if you have a tent or tent trailer. But as I said, very hard to predict
from year to year what the weather will be, can be a warm and sunny period at that time of year, or a cold and rainly period,
or a mixture of the two.
All three Valley campgrounds are similar, but Upper Pines is the largest, and tends to be the noisiest as well: more large groups
occupying multiple campsites, and having boisterous gatherings at night. Lower Pines is the smallest campground of the three,
and North Pines right behind it. But it's really a matter of personal preference, you can have good and bad experiences in any of them.
