Daisy Trail Hiking Access 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. The very mention of the the word Wyoming evokes the essence of the American West. Wyoming is all that innumerable movies, novels and legends have tried to capture. This Western Spirit thrives to this day in the Cowboy State. The name Wyoming has its origins in an Algonquin word meaning \"large prairie place \".
