Alternate way to hike Mt. Whitney!

Overall plan

   Here is the overall plan from Cottonwood pass to Whitney portal!  The total distance including Mt. Whitney summit is about 35 miles.  It is much longer than a simple round trip through Mt. Whitney trail which is about 22 miles.

   Typical plan is 3 days 4 nights on the trail.

Permit

   It requires a regular wildness permit to enter the trail from Cottonwood pass and an exit permit for the Mt. Whitney zone.
   I got the both permits after notified Mt. Whitney lottery result.   I still can book the both permits on the reservation site outside of the lottery.  That is much easier to get the permit for Mt. Whitney zone via Mt. Whitney trail.

   I heard it might be possible to get a permit with just walk-in on the day of the entrance at the visitor center in Lone Pine.  The person who told me this plan got permit a couple times in the past.

   So it would be a good alternate plan to hike Mt. Whitney without much hassle to get overnight permit for Mt. Whitney trail.
