OverviewMount Huntington can be found out of Rock Creek up in the Hilton Lakes basin area sharing a ridge with Mount Stanford and eventually with Mount Morgan (North). This peak has routes ranging from class 2 to class 3 on the majority of routes.
First ascent was on July 14, 1934 by David Brower, Norman Clyde, and Hervey Voge.
Getting ThereIf in the Mammoth/Bishop region, get on the 395 to Tom's Place and drive up Rock Creek Road to the Hilton Lakes / Davis Lake trail head. Head up the trail on the way to Hilton Creek Lakes. Follow this to the upper Hilton Creek Lakes all the way to Lake 10353. From here pick your route and head up.
There is another approach from the west from either Pioneer Basin or the Fourth Recess. These can be easily reached out of Rock Creek after heading over Mono Pass then north towards the peak.
Red TapeThis climb is within the John Muir Wilderness, so any overnight stays will require a permit. Due to high traffic through this area, from May 1st to November 1st a quota system is in effect. 60% of permits can be reserved ahead of time with a $5 per person fee and the other 40% of permits available on a first come first served basis starting 11am the day before the trip.
Bear canisters are required for overnight stay. In addition no campfires are allowed over 10,000ft.

CampingCamping either at Lake 10353 or one of the other Hilton lakes is very accessible and might be a better alternative instead of the decent hike in and out. If going for primarily Mount Huntington, Lake 10353 is the closest. Though it also can be done in one day and even linked by traverse to Standford or even Morgan by a fit fast moving party. The link to Mount Standford is much more doable.
Of course, camping is also possible on the west side in either Pioneer Basin or the Fourth Recess depending on the chosen ascent route.
