      Yellowstone National Park, encompassing 2.2 million acres, is one of America's premier wilderness areas. Most of the park is backcountry and managed as wilderness. Over 1,100 miles (1770 km) of trails are available for hiking. However, there are dangers inherent in wilderness: unpredictable wildlife, changing weather conditions, remote thermal areas, cold water lakes, turbulent streams, and rugged mountains with loose, "rotten" rock. Visiting wilderness means experiencing the land on its terms. If you choose to explore and enjoy the natural wonders of Yellowstone, there is no guarantee of your safety. Be prepared for any situation. Carefully read all backcountry guidelines and regulations.

      There are numerous trails suitable for day hiking. Begin your hike by stopping at a ranger station or visitor center for information. Trail conditions may change suddenly and unexpectedly. Bear activity, rain or snow storms, high water, and fires may temporarily close trails. At a minimum, carry water, a raincoat or poncho, a warm hat, insect repellent, sunscreen, and a first aid kit. It is recommended that you hike with another person.

      No permit is required for day hiking.

      Yellowstone has a designated backcountry campsite system, and a Backcountry Use Permit is required for all overnight stays. For more information on how to acquire permits, as well as important safety information, please visit the official Yellowstone websites at the links below.

      The Yellowstone trails in Trailforks are mapped broadly within the official backcountry regions (map in backcountry situation report linked below). The backcountry regions are Northwest, Northeast, Canyon, Central, Old Faithful, Southwest and Southeast.

      IMPORTANT: Before setting out, check the National Park Service's backcountry situation report (link below) for the most up-to-date information on park trails.
