Mt. Whitney Trailheads Every year thousands travel to Whitney Portal with their hearts set on attaining the summit of Mt. Whitney, the highest point in the contiguous United States. By far the most popular route on Mt. Whitney is the hiking trail built in 1904. To maintain the wilderness character of the hike and to prevent overcrowding there are daily quotas for the trail during the peak season. The 11 mile Whitney Trail leads to the highest peak in the "lower 48". It is the most frequently climbed peak in the Sierra Nevada, if not in the U.S. You'll find our Whitney Area Guide Map a good place to start your adventure.

HIGHEST ELEVATION -14,496 ft. (summit)
TRAIL DIFFICULTY- Moderate to Strenuous, especially to those not acclimated to high altitude. Altitude sickness can be a problem.

SEASON- Normally, the trail is free of snow from mid-July to early October. Ice patches frequently remain on the switchbacks above Trail Camp all summer long.

Wilderness Permits are required year-round for all overnight hikes and for day hikes past Lone Pine Lake.


Whitney Portal can be reached by driving 13 miles west of Lone Pine on Whitney Portal Road. Whitney Portal Road intersects Highway 395 at the traffic signal in downtown Lone Pine. The road is usually open from May to early November. In the winter, the last 6 miles of the road are not plowed.

The trail is rated moderate to strenuous, depending upon your experience and skill level. At high elevations, altitude sickness affects many people. You can put yourself in danger by pushing yourself past your physical limits. Headaches, dizziness and nausea are symptoms that should not be ignored. If you begin showing signs of altitude sickness you should descend to a lower elevation immediately.

WILDLIFE at Mt. Whitney

Many animals call the Mt. Whitney area their home. You may see black bears, marmots, squirrels and birds. Their diet consists of food obtained from the natural environment. When animals eat human food, it is unhealthy for them and it can change their behavior. In some cases it can spell death for the animal. Please help us in an effort to keep black bears, marmots and other animals from obtaining human food. Keep them out of your food and garbage b storing your food properly. Keep a good distance between you and wild animals. Do not try to approach or feed these animals. Hand feeding them puts your life, and theirs, at risk. Remember, you are a visitor to the place they call home; so treat them with respect. Please know how to store your food correctly -- it protects the wildlife and guarantees that you will not go hungry on your trip.


Summer days may be warm at lower elevations, but at higher elevations it will be cooler. You may need a down jacket in July, when it is 90 degrees at the trailhead. Even in summer the following conditions may exist: rain, wind, lightning, snow, ice and below freezing temperatures. Afternoon thunderstorms are common and may show no warning of their arrival. These storms build quickly and can occur daily. If clouds appear before noon, precipitation is likely to happen. Above tree line it is difficult to find shelter from lightning strikes. At the first signs of lightning, assess your situation and decide if you should turn around. Check the weather forecast before you start your trip.

Equipment needs vary according to the time of year, the condition of the trail and your mountaineering skills. Layered clothing, rain gear, good boots, sunglasses, sunscreen and a hat are advisable. At anytime of year one or more of the following may be recommended: crampons, ice ax, snowshoes, skis, ski poles and walking sticks. You and every member of your party should know how to use this equipment properly before hiking up the mountain. Only you will know what your specific equipment needs are for a successful hike. Be aware; you may need an ice ax on a section where another can easily walk without one. Knowledge of your safety gear may mean the difference between life and death.


The presence of Giardia in backcountry water poses a serious health problem. Filter, boil or chemically treat all drinking water. Water is available near the trail as far as Trail Camp. Carry water to the summit, as there is no dependable source of water after Trail Camp.


To help protect the water quality, there are toilets at Outpost Camp and Trail Camp. There is a pit toilet at the summit. The facilities at Outpost Camp and Trail Camp are for solid wastes only. Toilet paper is not supplied. If toilets are not available, please dispose of human waste at least 200 feet from water, and bury it in soil at least 6 inches (15 cm) deep, or pack it out. Pack out your toilet paper. Do not bury sanitary napkins or tampons; pack them out. A plastic bag with a seal works well.
