I always thought I a loner while out in the backcountry…until I went to a group meet with folks from this Forum. I really enjoyed the trip above Fresno at
Sample Meadow CG The campground might not have been the best, but the company was great and is something I’ll never forget. Still, I enjoy a trip up there in late October each year.
I know you asked for a single CG but after Labor day, a CG that always puts a smile on my face is
Tamarack Flat in Yosemite.
It’s usually vacant and finding a spot without people is no problem. Of course every now and then someone has to pick the camp right next to you even though there are open sites all over the place.
My favorite local summer spot has got to be
Leavitt Lake. Although not a full fledge CG, it seems like a spread out camp or busy boon dock spot. The spaces are very far apart from each other. At least I can beat the hottest days of the year up there plus the fishing is good.
My #1 winter camp is probably
Merced River Canyon
The temps are fairly mild and early winter to spring is great. People usually don’t start rolling in until the weather warms into the 70’s around Feb.
A good snow camp (provided it's plowed) is
Hodgdon Meadow. It's one spot that is usually empty when everything else is closed.
