If there are well-maintained trails, use them. Don’t take shortcuts between switchbacks. And if there’s living soil crust nearby, stay off it at all costs. When wilderness hiking, if there are no marked trails, don’t walk single-file, as you risk wearing a path where there shouldn’t be one. Pitch tents and set up camp on sandy surfaces, gravel, or hearty vegetation like dry grass if you’re camping in the backcountry where there are no designated campsites. Then when you leave, do your best to restore the area to what it looked like before you arrived. In a high-use campsite like those in state or national parks, stick to the well-worn areas that have been cleared specifically for camping.
