You'll go up over 8900 ft at the top of the pass. You can probably get to Kennedy Meadows coming from the east but not so sure about getting all the way over. It is gated on the west end coming up form Kernsville but not sure on the east end. I camped up that way about a month ago and it was cold. I also got caught in an early snowstorm headed north. Link to ride report with some pics of Nine Mile Canyon Road and Sherman Pass:
Great ride from Springville all the way over to Hwy 395. Good Luck.
