Leave No Trace

Leave No Trace

Working Together to Preserve Yosemite

To keep Yosemite National Park pristine and wild for future generations, we practice the Leave No Trace® philosophy—and encourage guests to follow our example. Together we can make a difference. 

1. Plan Ahead

Map out your trip in advance to avoid ecologically sensitive areas—and establish whether you'll need wilderness permits where you’ll be traveling. If you plan to backpack you will need a wilderness permit. For day hikes, permits are not required... unless you are hiking Half Dome then a Half Dome permit is required.” It is also a good rule of thumb to advise others when and where you will be hiking. 

2. Leave a Light Footprint

When hiking, make sure you stay on the designated paths and camp in designated camping areas. When putting down your tent for the night, ensure that you’re on durable ground to help prevent erosion and limit your impact.

3. Pack It In, Pack It Out

One of the most important things you can do to help preserve Yosemite National Park is to limit the amount of waste that you create — and bring all waste material with you to be thrown away at the end of your outdoor experience.

4. Take Only Pictures

Every flower, plant, and even every rock is there for everyone’s enjoyment and is part of Yosemite National Park. It’s important that you leave everything just as you find it and not take any “natural souvenirs” home with you.

5. Be Fire Smart

Keep your fires small and in control within the designated areas in the Park— and always use existing fire rings, which you can find in designated areas throughout the park. Before leaving your campsite fire, be sure that the fire is completely out. Even one glowing ember can start a forest fire.

6. Keep Wildlife Wild

Give animals their space, and never give them food. When animals become accustomed to human food, they lose their fear of humans — which is dangerous for people and animals.

7. Always Be Considerate

Each year about 4 million visitors come to Yosemite National Park to enjoy the tranquility and wilderness. Keeping your voices low and being respectful on the trail is an important part of being a good guest at Yosemite.
