The 7 Principles of Leave No Tra

The 7 Principles of Leave No Trace provide an easily understood framework of minimum impact practices for anyone visiting the outdoors. The Principles can be applied anywhere — from remote wilderness areas, to local parks and even in your backyard. Each Principle covers a specific topic and provides detailed information to empower you to minimize your impacts.

The 7 Principles are well-established and widely known but not static. Leave No Trace continually examines, evaluates, and reshapes the Principles and conducts research to ensure that they are up to date with the latest insights from biologists, land managers, and other leaders in outdoor education.
