Mount Whitney is the highest summit in the contiguous United States and the Sierra Nevada, with an elevation of 14,505 feet.

The summit of Whitney is on the Sierra Crest and near many of the highest peaks of the Sierra Nevada. The peak rises 10,778 feet (3,285 m) or just over two miles above the town of Lone Pine 15 miles to the east, in the Owens Valley.

The peak dramatically rises above the floor of the Owens Valley. It rises more gradually on the west side, sitting only about 3,000 feet (910 m) above the John Muir Trail at Guitar Lake. The mountain is partially dome-shaped, with its famously jagged ridges extending to the sides.


Climbing routes


The Smithsonian Hut Shelter on Whitney’s summit.

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.[21] The Forest Service holds an annual lottery for hiking and backpacking permits on the Mount Whitney Trail. Applications are accepted from February 1 through March 15. Any permits left over after the lottery is completed typically go on sale April 1.[22] Most hikers do the trip in two days which is still considered a strenuous endeavor. 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, and allowing one not to carry overnight camping gear (sleeping bag and tent) up the mountain. This is considered an “extreme” day hike, which normally involves leaving Whitney Portal before sunrise and 12 to 18 hours of strenuous hiking,[23] 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 late September).

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.


The “Mountaineer’s Route”, a gully on the north side of the east face first climbed by John Muir, is considered a scramble, class 3 The fastest recorded time up this route to the summit and back to the portal is 3 hours 10 minutes, by Jason Lakey of Bishop.

Technical climbs

The steep eastern side of the mountain offers a variety of climbing challenges. The East Face route, first climbed in 1931, is one of the Fifty Classic Climbs of North America routes and involves technical free climbing but is mostly class 4. Other routes range up to class 5.

South of the main summit there are a series of minor summits that are completely inconspicuous from the west but appear as a series of “needles” from the east. The routes on these include some of the finest big-wall climbing in the high Sierra. Two of the needles were named after participants in an 1880 scientific expedition to the mountain. Keeler Needle was named for James Keeler and Day Needle was named for William Cathcart Day. The latter has now been renamed Crooks Peak after Hulda Crooks who hiked up Mount Whitney every year until well into her nineties.

Know Your Season

Come prepared for severe weather It may be warm and sunny at the trailhead, but weather conditions can change quickly at higher elevations. Be prepared for high winds, subfreezing temperatures, rain or snow at any month.

May-June: The winter snowpack slowly recedes. Expect snow on the ground above Lone Pine Lake through Memorial Day weekend, and snow on the switchbacks above Trail Camp through June. Nights are usually still below freezing. Winter-like storms are still possible.

July-early September: The trail is usually snow free and the weather can be fair and pleasant. At elevations above Trail Camp, however, it is often cold and windy. Thunderstorms and lightning are a significant hazard. If thunderstorms are forecast, plan to leave the summit by noon. Be aware thunderstorms sometimes will occur early in the day. At the first sign of lightning, leave the summit area or exposed ridge tops.

Late September-October: Short days and cold temperatures make day hikes to the summit difficult. Storms may bring severe cold and snow.

November-April: Winter prevails, with deep snow and very cold temperatures. Winter storms may drop several feet of snow and have winds over 100 mph. The road to Whitney Portal is usually closed 8.3 miles from Lone Pine (at elevation 6,400 ft., about 3 miles from the trailhead) from midNovember to late April.

FALL Conditions

  • Crampons and ice axe should be used when there is snow and ice on the trail.
  • From the cables to Trail Crest there are hazardous areas where a slip or fall can lead to injury or a fatality.
  • Snowfall on the Whitney Trail after mid-September may not melt off from the upper elevations.
  • Your ascent and descent will take longer than on dry trail.
  • Plan extra time into your itinerary.
  • Be prepared to climb on firm, hard, and slick snow, especially once the sun leaves the north-facing slope above Trail Camp (the entire slope is in shadow by mid-afternoon).
  • Snow and ice on the trail require you to have learned & practiced how to walk with crampons and how to self-arrest with an ice axe.
  • Ski poles are no substitute for an ice axe; you will not be able to self-arrest if you fall. Sliding down the snow on your bottom (glissading) from Trail Crest is not a safe option.
  • The slope angle and underlying ice will likely cause you to slam into rocks at high speed. There have been injuries and fatalities here due to glissading.
  • Just because someone else decided to summit in questionable conditions should not determine what you decide to do. You need to make your decisions based on your skills and the abilities of the weakest member of your group.

Campground and trailhead Always use the food storage lockers at the campgrounds and the trailhead. Space is limited, so minimize the amount of food you store and don’t place non-food items in lockers.

Please leave ice chests at home. To bears, “food” includes water bottles, coffee mugs, soda cans, trash, wrappers, cosmetics, grocery bags and ice chests. Do not leave these “food” items in your car or tent. Keep a clean camp and never leave trash or food unattended.

To discourage bears from entering your camp at Whitney Portal, finish your meals and store all food items in the lockers by nightfall. Always keep your pack or food within your immediate reach at Whitney Portal.

Bears have been known to take packs left next to vehicles while hikers set up camp or went inside a restroom On the trail Bear canisters are required on the Mt. Whitney Trail from Memorial Weekend to November 1. Bear canisters are the only effective means to store your food.

We strongly recommend you use a bear canister throughout the year. Bears may be active during spring and fall, and marmots will attempt to get improperly stored food. Before you leave the trailhead, make sure that all food, trash, toiletries and anything with a scent will fit inside the canister the first night.

Forest Service rangers will issue citations to hikers that counterbalance food or hang trash from trees when canisters are required.

Bear canister rental locations: InterAgency Visitor Center in Lone Pine; Whitney Portal Store; and sporting goods stores in Lone Pine.

Why can’t I just bury my poop, like in other wilderness areas?

First, consider there are over 20,000 people on the mountain each year. Then consider that much of the area is solid bedrock. There is simply not enough soil to decompose the human waste from this many hikers. And with limited soils to filter waste, there is the potential to harm water quality. Remember, you need to drink the water too.

On Mt. Whitney, pack-out kits are the only acceptable method for the disposal of human waste, year-round. Please do not bury your waste in the snow. Once the snow melts, your waste is an unhealthy and unsightly affront to everyone’s wilderness experience.

Where to get pack-out kits InterAgency Visitor Center in Lone Pine (cost of the kit is paid through permit reservation fees).

How to use a pack-out kit † Find a secluded location. † Spread the large inner bag on the ground. Don’t spill the powder! † Crouch over the bag and relieve yourself. Dispose of toilet paper in the bag. † Tie a know in the inner bag. Then zip lock it inside the outer bag. Fight Odors: Add a cup of water or urinate in the inner bag. The powder inside absorbs liquid to create an odor-fighting gel.

Urine: Urinate on bare ground or rocks (not plants), and stay at least 100 feet from water or campsites. It is okay to urinate inside the pack-out kits.

Animals: Store only human waste and tissue in your pack-out kit. Trash or food scraps will attract animals. Storage: Store used kits outside your tent or in your pack. Do not store kits in bear canisters.

Hygiene: Wash your hands after using pack-out kits and before eating or preparing food. Disposal: Dispose of used kits only at the receptacle at the trailhead, next to the trailhead toilet.


You do not have to camp Outpost Camp or Trail Camp. Other choices include Lone Pine Lake or Consultation Lake. Always choose a well-established site. Please comply with signs that indicate areas closed to camping, and do not build rock walls around your campsite. Outpost Camp: Located in Bighorn Park 3.8 miles from the trailhead at elevation 10,300 ft. Relatively sheltered campsites are located on a gravel flat amidst trees and willows. Additional sites are located at the west end of Bighorn Park, north of Lone Pine Creek. Trail Camp: Located 6 miles from the trailhead at elevation 12,000 ft., Trail Camp is above tree line and exposed to wind. Campsites are scattered off both side of the trail. Look in the granite slabs south or east of the tarn at Trail Camp for a more secluded campsite. Regulations to protect the wilderness † Camp more than 100 feet from lakes, streams, or the trail. † No camping at Mirror Lake or Trailside Meadow. † No campfires. † Do not wash or discharge soap within 100 feet of lakes or streams. † Do not leave trash in the wilderness. † Use your pack-out kit for human waste. † Do not urinate within 100 feet of lakes, streams, or campsites.

Plan for High Altitude

Arrive a few days early: Stay at a campground located at a moderate (8,000 – 10,000 ft.) elevation: Whitney Portal, Onion Valley, or Horseshoe Meadows. Day hike to higher elevations: You will acclimate better by day hiking at higher elevations and sleeping at moderate elevations. We recommend you take acclimation hikes at Horseshoe Meadows or Onion Valley to lessen the number of people on the Whitney Trail. Travel at a slow, steady and comfortable pace: If you are day hiking to the summit, start up the trail well before dawn. Stay hydrated and well nourished: Be sure to replenish electrolytes. Don’t forget any prescribed medications. Recognize Acute Mountain Sickness (AMS): Also called altitude sickness, AMS symptoms include

Don’t forget any prescribed medications. Recognize Acute Mountain Sickness (AMS): Also called altitude sickness, AMS symptoms include persistent headache along with difficulty sleeping, dizziness, fatigue, loss of appetite, nausea or vomiting. AMS can affect anyone. Your age, gender, physical condition or previous high altitude experience has no bearing on whether you will be affected by AMS. If you experience more than mild discomfort from AMS, you should descend immediately. † AMS symptoms will worsen if you continue to ascend. † AMS may impair your judgment. Your group’s safety depends on everyone making good decisions on the mountain.
