I'm planning a trip to Yosemite for late October and am looking for some suggestions.
Firstly, I'm looking for a good hike, something in the range of 10-15 miles round trip. Preferably in the Valley. I've done the Mist Trail and Upper/Lower Falls, however those were both during the spring. I don't imagine those trails are ideal for the fall due to the lack of water. Any suggestions for trails which are particularly scenic in the Autumn?
Secondly, I have a reservation at Upper Pines campground. They say that the maximum number of people is 6. Does anybody know how strictly this is enforced?
Thanks in advance!
