trailhead camping at mono pass trailhead yosemite

[overheadx2]

I did the hike from TM to the valley 2 years ago and after getting my permit headed for the back packer camp. When I got there, I would say that 1/3 were just walk in camping with chairs, large tents and coolers, 1/4 were cycling and the rest were backpackers. There was no spaces left so we camped off to the side a ways. The ranger came by and advised us it was not a spot so I told her as soon as she checked permits we would surely have a site to camp. She looked around and then decided we were fine where we were. Very friendly crowd which is nice since you may have to spoon up with other campers and share a box. Get there as early as possible mid summer.

You asked about having permit in hand before entering? The rules state that you are supposed to have permit in hand before, but...
If you come in by bus, no permit needed -
If you ride a bike in, no permit needed,
and finally, if you have your printed notification, come in after the Wilderness office closes, and follow (rule #1), no further permit will be needed. Yosemite is enlightened, a great attitude towards real backpackers. Jen, head wilderness ranger Tuolumne, will size you up in seconds. (I could write stories.) Don't blow it with attitude. If in the Valley, say hi to Ranger Dave, head bear honcho and almost a fisherman.
If leaving/parking a car in Valley (always nice to hike to the car) - Curry Orchard is safe w/ convenient bear boxes and Shuttle bus friendly.

FYI - I just received my emailed Wilderness Permit Reservation Confirmation from Yose and was pleased to see, "This confirmation email provides authorization for you to stay in a backpackers campsite in park campgrounds one night before and one night after your trip. The cost is $5.00 per person per night."
