Henry M. Jackson Wilderness

General Contacts Area Management Wilderness Laws

Area Management

The Henry M. Jackson Wilderness is part of the 110 million acre National Wilderness Preservation System. This System of lands provides clean air, water, and habitat critical for rare and endangered plants and animals. In wilderness, you can enjoy challenging recreational activities like hiking, backpacking, climbing, kayaking, canoeing, rafting, horse packing, bird watching, stargazing, and extraordinary opportunities for solitude. You play an important role in helping to "secure for the American people of present and future generations the benefits of an enduring resource of wilderness" as called for by the Congress of the United States through the Wilderness Act of 1964. Please follow the requirements outlined below and use Leave No Trace techniques when visiting the Henry M. Jackson Wilderness to ensure protection of this unique area.

General Wilderness Prohibitions

Motorized equipment and equipment used for mechanical transport is generally prohibited on all federal lands designated as wilderness. This includes the use of motor vehicles, motorboats, motorized equipment, bicycles, hang gliders, wagons, carts, portage wheels, and the landing of aircraft including helicopters, unless provided for in specific legislation.

In a few areas some exceptions allowing the use of motorized equipment or mechanical transport are described in the special regulations in effect for a specific area. Contact the Forest Service office or visit the websites listed for more specific information.

These general prohibitions have been implemented for all national forest wildernesses in order to implement the provisions of the Wilderness Act of 1964. The Wilderness Act requires management of human-caused impacts and protection of the area's wilderness character to insure that it is "unimpaired for the future use and enjoyment as wilderness." Use of the equipment listed as prohibited in wilderness is inconsistent with the provision in the Wilderness Act which mandates opportunities for solitude or primitive recreation and that wilderness is a place that is in contrast with areas where people and their works are dominant.

Wilderness-Specific Regulations

Wilderness managers often need to take action to limit the impacts caused by visitor activities in order to protect the natural conditions of wilderness as required by the Wilderness Act of 1964. Managers typically implement 'indirect' types of actions such as information and education measures before selecting more restrictive measures. When regulations are necessary, they are implemented with the specific intent of balancing the need to preserve the character of the wilderness while providing for the use and enjoyment of wilderness.

The following wilderness regulations are in effect for this area. Not all regulations are in effect for every wilderness. Contact the Forest Service office or visit the websites listed for more specific information about the regulations listed.


Maximum party-size is 12 in a group. A group is any combination of people and pack and saddle animals. Dogs are not counted as part of the group size limit.

Any type of wheeled conveyance designed for the purpose of transporting persons, gear, equipment, or game animals is prohibited. Mobility impaired individuals whose sole means of locomotion is by wheelchair are exempt from this regulation.

Shortcutting trail switchbacks is prohibited. This practice damages the trail, soil, and vegetation.

It is prohibited to leave any equipment and supplies, including geocaches, unattended for more than 48 hours.

Protect restoration work. Some areas are closed to allow the natural vegetation a chance to recover after years of heavy recreation use. Do not walk or camp in areas closed for restoration.

Cutting of standing green trees, snags, and boughs is prohibited. Healthy trees and decrepit snags are beautiful and important components of the ecosystem. Lightweight sleeping pads, tents, and campstoves make this practice unnecessary.

Pack out all your litter and whatever you can carry that was left behind by those more careless than you. If you are in an area where fires are allowed, remove all non-combustibles such as foil and glass from fire rings. Never put litter into a backcountry toilet.



Camping is prohibited within 200 feet, horizontal distance, from the shoreline of the following lakes: Goat Lake, Blanca Lake, Pear Lake.


Campfire, except for self-contained, carry-in devices such as stoves, are prohibited within 1/4 mile of the following locations: Goat Lake, Glacier Basin Trail, Silver Lake, Upper Twin Lake, Lower Twin Lake, Lake Sally Ann, Lake Minotaur, Lake Theseus, Heather Lake, Glasses Lake, Lake Valhalla.



All feed including hay, hay cubes, straw, grain or other crop or mulch products must be certified weed free. Bales, containers, or sacks must be tagged with the proper weed-free identification as required by the product's state of origin, or you must have the original and current state documents that certify the hay or crop products meet or exceed the North American Weed Management Association or comparable certification standard. This regulation does not apply to commercially processed feed (feed pellets or steamed, rolled grains).


Some trails are closed to use by pack and saddle stock due to steep grades, inadequate design, lack of grazing or other factors. Pack animals include all horses, mules, burros, donkeys, llamas, goats, and other animals commonly used for packing gear or carrying a rider.

Consult specific trail closure information at AND


Grazing, hitching, tethering, or hobbling any pack and/or saddle livestock within 200 feet of a lake shore is prohibited. This includes all horses, mules, burros, donkeys, llamas, goats, and other animals commonly used for packing gear or carrying a rider.

The following user fee system(s) have been implemented for this wilderness: TRAILHEAD PARKING.

Contact the Forest Service office or visit the websites listed for more specific information on this fee system.
