we hiked this from west to east 15 years ago, begining at the wolverton trailhead in sequoia. the high sierra trail. well traveled, well marked. tho if you go early season snow will make route finding more complicated.
we did it in 5 days during august. i remember the first day being pretty tough but the rest was relaxing. such a diverse and beautiful range. hope you get a chance to do it! thanks for reminding me of an amazing trip.
not sure but it might be easier to get a permit going west to east, considering the popularity of the whitney trail. unless you go mountaineer's route.
pretty simple hike, just gotta make a plan to get home! my dad, was kind enough to give us a lift to sequoia! then we hitch hiked back to so cal from lone pine.
