Maximum group size in the Yosemite wilderness is 15 people on trails and 8 people maximum for any off-trail travel.
Please use existing campsites at least 100 feet from lakeshores and streams to minimize pollution and vegetation impact. Camp four trail-miles from Tuolumne Meadows, Yosemite Valley, Glacier Point, White Wolf, Hetch Hetchy, and Wawona, and at least one trail-mile from any other road.
Bury human waste six inches deep in a small hole at least 100 feet from any lake, stream, or camp area. Toilet paper should be burned or packed out.
Pack out all garbage (no exceptions). Do not bury garbage, scatter organic waste, or leave foil in campfire sites.
Use gas stoves rather than wood fires. Wood fires are not permitted above 9,600 feet due to firewood scarcity. Use only existing fire rings and dead and down wood in areas below 9,600 feet.
Dogs and other pets are not allowed in the Yosemite wilderness.
Putting soap, including bio-degradable soap, or any form of pollutant into lakes or streams is prohibited. Discard wash and rinse water at least 100 feet from water sources.
Firearms are not permitted in the wilderness.
Visit the Wilderness Center
At the Wilderness Center, just east of the Visitor Center on the pedestrian mall in Yosemite Valley, detailed information is available about the park’s wilderness, there are educational displays, a trip planning section is provided, and guidebooks, maps, and backpacker supplies are offered for sale.

Treat the Water
Unfortunately, microscopic organisms known as Giardia lambilia are present in wilderness lakes, rivers, and streams. They can cause illness (sometimes quite severe), so you should not drink from these sources without first treating the water. Your options are to boil it for three minutes, to use a chemical disinfectant, like iodine or chlorine (less effective than boiling), or to use a Giardia-rated water filter available from outdoor equipment stores, at the Wilderness Center, or from the Yosemite Store online.
Many wilderness trips begin at elevations much higher than you may be accustomed to and then go even higher. It’s a good idea to arrive a day early to let your body adapt to the thinner air. Don’t over-exert, and drink plenty of fluids to avoid altitude sickness.
Bear-Proof Your Campsite
Yosemite’s black bears are clever and very persistent. If you fail to set up your camp and store your food properly, your whole trip can be ruined. Always follow these six steps:
1. Use the food storage boxes at your trailhead for keeping any food that you will not be taking on your backpack trip. Never leave food or food-related supplies in vehicles left overnight at trailheads.
2. Store your food in a bear-resistant food storage container. Weighing just 2.9 pounds and holding from 5 to 7 days worth of food for one person, the canisters are strongly encouraged by the National Park Service, and required above 9,600 feet. They are for sale and rent at the Wilderness Center, the Curry Village Mountain Shop, and the Village Sports Shop in Yosemite Valley, at the Crane Flat Store, at the Tuolumne Reservation Cabin and the Mountaineering School in Tuolumne Meadows, at the Wawona Information Station and the Wawona Store, at the Big Oak Flat Information Station, and at the Hetch Hetchy Information Station.
3. Hang your food and anything with an odor as instructed by the NPS if you don’t use a canister. Hang pots and pans from food bags as an alarm. Sleep 20 to 30 feet from where you hang items so you can hear the bear and scare it away as quickly as possible.
4. If a bear approaches your camp, act immediately to scare it away. Yell and make as much noise as possible. Throw small rocks no larger than golf balls at the bear. Make noise and chase the bear. Multiple people chasing a bear increases effectiveness.
5. Always maintain a distance. Do not advance on a bear that appears to feel threatened or cornered by you. Do not attempt to retrieve food or gear from a bear until the item is abandoned.
6. Food taken by bears is your responsibility. Please clean up and report all bear damage to a ranger. Improper food storage can result in the killing of conditioned bears, personal injury, and property loss. Please do your part to keep Yosemite’s bears wild.
