Yellowstone National Park is one of America's premier wilderness areas. The park encompasses more than 2.2 million acres, has more than 1,100 miles (1,770 km) of hiking trails, and is primarily managed as wilderness. Day hiking does not require a permit. When planning a hike, remember that many of Yellowstone’s trails are more than 7,000 feet above sea level. Most areas retain snow until late May or early June, and some (especially mountain passes) are snow-covered until late July. Also, many routes require fording rivers that can be 25 feet wide, 3 to 6 feet deep, extremely cold, and swiftly running during our late spring runoff. It’s hard to tell from a map whether a stream will be a raging torrent or merely a swollen creek. Check our Backcountry Conditions Page for the most up-to-date information on park trails.
