Is there hiker parking at the Onion Valley trailhead? Figure leaving my car there would be best, then arrange to get back to pickup my car after my hike. That also leaves my car available for an abort back to Onion Valley if needed.
I left my car at the Onion Valley trailhead for 5 nights. I started there, went over Kearsarge Pass, took JMT to Whitney, and exited at Whitney Portal. Lots of parking, water faucets, bear lockers, and a campground that you can not only reserve sites but they keep several for walk-in hikers.
