Things To Do


Long before any recorded human history in Yellowstone, a massive volcanic eruption spewed an immense volume of ash that covered all of the western U.S., much of the Midwest, northern Mexico and some areas of the eastern Pacific. The eruption dwarfed that of Mt. St. Helens in 1980 and left a caldera 30 miles wide by 45 miles long. That climactic event occurred about 640,000 years ago, and was one of many processes that shaped Yellowstone National Park--a region once rumored to be the place where hell bubbles up. Geothermal wonders, such as Old Faithful, are evidence of one of the world's largest active volcanoes. These spectacular features bemused and befuddled the park's earliest visitors, and helped lead to the creation of the world's first national park. Fur trappers' fantastic tales of cauldrons of bubbling mud and roaring geysers sending steaming plumes skyward made their way back east.

Several expeditions were sent to investigate, opening the West to further exploration and exploitation. In 1871, Ferdinand Hayden led an expedition that included artist Thomas Moran and photographer William H. Jackson. They brought back images that helped convince Congress that the area known as Yellowstone needed to be protected and preserved. In 1872, President Ulysses S. Grant signed a law declaring that Yellowstone would forever be dedicated and set apart as a public park or pleasuring ground for the benefit and enjoyment of the people.

  • Climbing

    There are many climbing opportunities at the park. Since it is so big, make sure you are aware of seasonal closures before planning your climbing trip.

  • Fishing

    Yellowstone National Park is managed to protect cultural and natural resources and outstanding scenery, and to provide for visitor use. Fishing has been a major visitor activity for well over a century. Because of this history, fishing continues to be allowed and can complement, and in some cases even enhance, the park's primary purpose to preserve natural environments and native species.

    The fishing season begins the Saturday of Memorial Day weekend (usually the last weekend in May) and extends through and includes the first Sunday in November.

  • Hiking

    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.

    Do note that a Backcountry Use Permit is required for all overnight trips in the backcountry.

  • Historic Sites

    The park is home to several historic lodges and buildings. Park rangers and concessioners lead tours that focus on a variety of cultural and historical topics. Visitor centers are also a great place to learn about park history.

  • Horseback Riding

    Horseback riding is best in spring or summer. Available at Mammoth, Tower-Roosevelt, and Canyon.

  • Picnicking

    Visitors can use picnic areas throughout the park. Signs along the roadway indicate picnic areas. Every picnic area has tables, most have vault toilets. You can use camping stoves and self-contained charcoal grills to prepare food at any picnic area. Fires are permited only in picnic areas with fire grates. Only one picnic area--Madison--has water. Camping is not allowed in any picnic area.

  • Water Sports

    Swimming is allowed in some areas. Swimming or bathing is prohibited in hydrothermal pools or streams where water flows entirely from a hydrothermal spring or pool. Where swimming is allowed, swim at your own risk.

  • Wildlife Watching

    More plants and wild animals live in Yellowstone, in their natural habitat, than anywhere else in the lower 48 states. Animals you may spot during your trip include elk, bison, moose, otters, trumpeter swans, black bears, grizzly bears, wolves, and coyotes.

  • Winter Sports

    A winter visit to Yellowstone National Park will give you lasting memories of snowy landscapes, steaming geyser basins, and incomparable wildlife viewing. Skiing and snowmobiling are the most popular.

    Park concessioners operate lodging and provide other services, including evening programs, snow-coach tours, guided ski and snow-shoe tours, guided snowmobile tours, and wildlife bus tours. Detailed information is available at the visitor centers, warming huts, and front desks of hotels or by calling Xanterra Parks & Resorts at (307) 344-7311.

    The winter snowmobiling season in Yellowstone National Park ends around mid-March.


Summer: Daytime temperatures are often in the 70s (25C) and occasionally in the 80s (30C) in lower elevations. Nights are usually cool and temperatures may drop below freezing at higher elevations. Thunderstorms are common in the afternoons. Winter: Temperatures often range from zero to 20F(-20 to -5C) throughout the day. Sub-zero temperatures over-night are common. The record low temperature is -66F (-54C). Snowfall is highly variable. While the average is 150 inches per year, it is not uncommon for higher elevations to get twice that amount. See Winter Daily Reports.

Spring & Fall: Daytime temperatures range from the 30s to the 60s (0 to 20C) with overnight lows in the teens to single digits (-5 to -20C). Snow is common in the Spring and Fall with regular accumulations of 12" in a 24 hour period. At any time of year, be prepared for sudden changes. Unpredictability, more than anything else, characterizes Yellowstone's weather. Always be equipped with a wide range of clothing options. Be sure to bring a warm jacket and rain gear even in the summer.
