The most popular route to the summit is by way of the
Mount Whitney Trail which starts at
Whitney Portal, at an elevation of 8,360 ft (2,550 m), 13 mi
(21 km) west of the town of Lone Pine. The hike is about 22 mi
(35 km) round trip with an elevation gain of over 6,100 ft
(1,900 m). Permits are required year round, and to prevent overuse a
limited number of permits are issued by the
Forest Service between May 1 and November 1.
Most hikers do the trip in two days. Those in good physical
condition sometimes attempt to reach the summit and return to
Whitney Portal in one day, thus requiring only a somewhat
easier-to-obtain "day use" permit rather than the overnight permit.
This is considered an "extreme" day hike, which normally involves
leaving Whitney Portal before sunrise and 12 to 18 hours of
while struggling with
altitude sickness, cold air, and occasionally treacherous
surface conditions (because snow and/or ice are normally present on
parts of the trail, except for a short period from early July to
Longer approaches to
Whitney arrive at its west side, connecting to the Mount Whitney
Trail near the summit by way of the
John Muir Trail.
