Route Breakdown
Trailhead to Lone Pine Lake (2.8 miles)
This first stretch eases you into the elevation gain with gradual switchbacks through forest. Lone Pine Lake offers a scenic resting point and is the last section that doesn’t require a permit.
To Outpost Camp (3.8 miles)
At about 10,400 feet, Outpost Camp is a popular overnight spot with a reliable water source. Expect meadows, small waterfalls, and increased exposure to sun and wind.
To Trail Camp (6.3 miles)
Trail Camp, located at ~12,000 feet, is the final staging area before the summit push. Camp here for acclimatization if doing an overnight hike. It’s near Consultation Lake and surrounded by granite walls.
99 Switchbacks to Trail Crest
Between Trail Camp and Trail Crest lie the infamous “99 Switchbacks.” This 2.2-mile section gains over 1,600 feet. It’s physically and mentally demanding, especially at altitude. Carry water from Trail Camp—this is a dry stretch.
Trail Crest to Summit (2 miles)
Once at Trail Crest (13,600 ft), you’ll cross into Sequoia National Park. A knife-edge ridge with dramatic drop-offs leads to the final summit approach. The trail narrows and becomes rocky and exposed. The views at the top are vast and unforgettable.
Summit!
At 14,505 feet, the Mount Whitney summit offers panoramic views and the famous Smithsonian shelter. Most hikers spend 15–30 minutes here before starting their descent. Remember: you’re only halfway done!
