Plan Ahead and Prepare
- Know the regulations and special concerns of Yosemite.
- Prepare for extreme weather, hazards, and emergencies.
- Schedule your trip to avoid times of high use.
- Visit in small groups. Split larger parties into smaller groups.
- Repackage food to minimize waste.
- Use a map and compass to eliminate the use of rock cairns or flagging.
Travel and Camp on Durable Surfaces
- Durable surfaces include established trails and campsites, rock, gravel, dry grasses or snow.
- Obey camping restrictions near lakes, streams, trails, other campsites, and historic and cultural sites and structures.
- Good campsites are found, not made. Altering a site is not necessary.
- Concentrate use on existing trails and campsites.
- Walk single-file in the middle of the trail, even when wet or muddy.
- Keep campsites small. Focus activity in areas where vegetation is absent.
Dispose of Waste Properly
- Pack it in, pack it out. Inspect your campsite and rest areas for trash or spilled foods. Pack out all trash, leftover food, and litter.
- Deposit solid human waste in catholes dug six inches deep at least 100 feet from water, camp, and trails. Cover and disguise the cathole when finished.
- Pack out toilet paper and hygiene products.
- To wash yourself or your dishes, carry water 100 feet away from streams or lakes and use small amounts of biodegradable soap. Scatter strained dishwater.
Leave What You Find
- Preserve the past: examine, but do not touch, cultural or historic structures and artifacts.
- Leave rocks, plants and other natural objects as you find them.
- Avoid introducing or transporting non-native species.
- Do not build structures, furniture, or dig trenches.
Minimize Campfire Impacts
- Campfires can cause lasting impacts to the backcountry. Instead, consider using a lightweight stove for cooking and a candle lantern for light.
- Use established fire rings or fire pans.
- Keep fires small. Only use sticks from the ground that can be broken by hand.
- Burn all wood and coals to ash and put out campfires completely.
- Observe wildlife from a distance. Do not follow or approach them.
- Never feed animals. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
- Protect wildlife and your food by storing rations and trash in bear canisters.
- Leave pets at home.
- Avoid wildlife during sensitive times: mating, nesting, raising young, or winter.
Be Considerate of Other Visitors
- Respect other visitors and protect the quality of their experience.
- Be courteous. Yield to other users on the trail.
- Step to the downhill side of the trail when encountering pack stock.
- Take breaks and camp away from trails and other visitors.
- Let nature’s sounds prevail. Avoid loud voices and noises.
