Mount Whitney can be summited as a day hike or multi-day backpack trip on the classic Mt. Whitney Trail. Located on the eastside of California's beautiful Sierra Nevada Mountains, the trail starts in Inyo National Forest and enters Sequoia National Park, with spectacular views and access to trails that continue deep into the park wilderness. The summit of Mt. Whitney is the southern end of the John Muir Trail. Named for the naturalist, author and early wilderness preservation advocate for preservation of wilderness, the John Muir trail extends more than 200 miles north to reach Happy Isles in Yosemite Valley. Whether you are seeking a one day hiking challenge, an overnight ascent, or beginning the trek of your dreams, climbing Mt. Whitney is sure to be a memorable experience.

Starting at 8,300 feet above sea level at Whitney Portal, the Mt. Whitney Trail gains over 6,200 feet of elevation. The trail is usually snow free from July to late September. Specialized equipment and training may be necessary to safely climb when snow or ice is on the trail.

Most day hikers choose the classic Mt. Whitney Trail. The 22-mile round-trip hike will challenge even very fit hikers. Expect to hike 12 to 14 hours to the summit and back. Consider starting before sunrise. Be prepared to hike in the dark.

For the backpacker starting up the Mt. Whitney Trail, some popular camp locations are Lone Pine Lake, Outpost Camp, Consultation Lake and Trail Camp. If you are approaching Mt. Whitney from a different route, you need a different permit. For more about other permits to Mt. Whitney click here .

Anyone considering other climbing routes should research the difficulty. The approach to the Mountaineers Route is steep, rugged and hard to follow. This route crosses the Ebersbacher Ledges to reach Boy Scout Lakes. Above Iceberg Lake there are several routes of varying technical difficulty. There is not a trail to the summit from this isolated canyon. The Mt. Whitney Trail overnight permit does not give access to the North Fork area. Mountaineers who wish to base camp near Iceberg or Boy Scout Lakes need an overnight permit specifically for the North Fork of Lone Pine Creek Trail.

Visitors to the Mt. Whitney Zone are expected to pack out their solid human waste.

    Know Before You Go

    Seasonal Information
    Choose your dates wisely. The Mt. Whitney Trail is a non-technical, but strenuous, route to the summit of Mt. Whitney when it is free of snow. Winter mountaineering skills and equipment are necessary for safe travel when snow is on the mountain.

    • 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. There was snow on the trail until after July 4th in 2011.

    • July-early September: The trail is usually snow free and the weather can be fair and pleasant. At elevations above Trail Camp, 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 with high winds and snow deposits from a few inches to several feet. Thin snow may melt quickly, but deeper drifts may linger for the winter. Winter mountaineering equipment and skills are necessary for safe travel when snow is on the mountain.

    • 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 mid-November to late April. Experienced winter mountaineers should be suitably equipped for extreme conditions and check avalanche conditions and weather forecasts.

    This is an Active Bear Area! Be alert when arriving at night. DO NOT leave food or refuse in your car. Do not leave food or your pack unattended.
    • At Whitney Portal: All food and scented items must be removed from vehicles and stored in the bear proof lockers located in parking areas. Dispose of trash in bear resistant trash cans.
    • On the trail: Day hikers, keep your pack with you at all times. Overnight hikers, bear resistant containers are required for storage of all food and trash.
