Refrain from going off the trail. Switching to a new trail might help increase erosion while detouring on a muddy trail would likely destroy the surrounding vegetation.

In Canada particularly, it is best to stay above the tree line unless you want to find yourself struggling on fragile wildflower, alpine moss and lichen.

Certain places in Canada have high forest fire index. In case you are in such places or anywhere near it, please refrain from building fire without using special camp fire containers.
