I have 2 questions: 1. Is it a feasible option to plan Mt. Whitney Summit hike on the weekend of 21-22 Oct 2017? 2. If yes, I know this may sound silly, will I be able to find a group that has permit somehow?
1. Yes, if the weather stays dry. 2. No. Groups don't normally invite strangers to join. But there is currently a single day hike permit available online for Oct 22. Keep checking, and you may find one for Oct 21, if that's what you want.
Overnight permits are usually available free to anyone walking in at the Visitor Center in Lone Pine in October.
