A fee is charged for a confirmed wilderness permit reservation. This fee is necessary to defray some of the costs of the reservation system. If you are requesting more than one permit, you must submit SEPARATE checks. Do not submit duplicate requests. They will be returned.

Due to it's popularity, the amount of hikers on the trail are limited by a quota for the Mt. Whitney Trail from May 1 though November 1. The entire daily quota is reservable in advance and day-of-hike cancellations are difficult to obtain. The Whitney Portal area is not part of the wilderness and contains developed campgrounds, a store, a fishing pond, and picnic area. Your permit does NOT cover overnight stays in this area. A fee is charged for camping at Whitney Portal.

All Inyo Forest Trailheads in the Ansel Adams, John Muir, and Dinkey Lakes Wildernesses now have entry quotas. Sample Meadow, Deer Creek, Billy Creek, and Potter Pass in the Kaiser Wilderness as well as Cottonwood Pass in the Golden Trout Wilderness also have entry quotas. Quotas apply to all overnight visitors, whether you use the services of a commercial outfitter/guide or not. Some trails have specific commercial quotas and all visitors using a commercial outfitter or guide must obtain their permit through the commercial operator. Some trails have single quotas where all commercial and non-commercial visitors must compete for the quota space.

Quotas will be in effect from May 1st to November 1st for the John Muir, Ansel Adams, and Dinkey Lakes Wildernesses. The Cottonwood Pass trail in the Golden Trout Wilderness and the above mentioned trails in the Kaiser Wilderness will remain the last Friday in June through September 15.

The methods of obtaining reservations for quota space differ between east and west side entry points, and is described below. If you are using the services of any commercial outfitter/guide for any activity including backpacking, mountain climbing, and horse packing, the commercial operator must reserve quota space for you. For each non-commercial quota 60% of the quota is available for advanced reservation. The remaining 40% is available for walk-in on a first-come, first-served basis, no fee charged. Commercial quotas are 100% reservable.

There is a fee of $5 per person to make a reservation. It is due at the time the reservation is booked and is not refundable. Mt. Whitney trail reservation fees remain $15 per person.

These quotas are in effect to protect the wilderness resource and to provide a quality backcountry experience to the visitor.

Unless prior arrangements are made, any reserved permits not picked up are cancelled and made available to others on a first-come, first-served basis. Reserved permits may be claimed up to 24 hours in advance, but entry into the wilderness is allowed ONLY on the entry date stated on the permit.

Help protect the wilderness resource by camping and burying human waste at least 100 ft. away from water and meadows. LEAVE NO TRACE. Pack out what you pack in, plus some more!

Trails are usually snow-free from early July through mid-October. BE PREPARED FOR RAIN, HAIL OR SNOW ON ALL HIKES, EVEN DAY HIKES. Afternoon thunderstorms are common in the summer and often have lightning. Hiking Supplies , rain gear, good boots, warm clothes and a first aid kit are essential.

All water in the Sierra Nevada should be treated for Giardiasis, a water-born cyst that causes severe intestinal disorders. Boil or filter all water.

Campfires are prohibited in many areas in the Eastern Sierra due to scarcity of fuel wood or other factors. Generally, campfires are discouraged in the wilderness. Where campfires are permitted, use only DEAD AND DOWNED wood, keep fires small and make sure fires are out with water, not dirt.
