Yellowstone
National Park

Horizontal Rule

By Act of Congress on March 1, 1872, Yellowstone National Park was "dedicated and set apart as a public park or pleasuring ground for the benefit and enjoyment of the people" and "for the preservation, from injury or spoilation, of all timber, mineral deposits, natural curiosities, or wonders. . . and their retention in their natural condition." Yellowstone is the first and oldest national park in the world.

The commanding features that initially attracted interest, and led to the preservation of Yellowstone as a national park, were geological: the geothermal phenomena (there are more geysers and hot springs here than in the rest of the world combined), the colorful Grand Canyon of the Yellowstone River, fossil forests, and the size and elevation of Yellowstone Lake.

The human history of the park is evidenced by cultural sites dating back 12,000 years. More recent history can be seen in the historic structures and sites that represent the various periods of park administration and visitor facilities development.

Ninety-nine percent of the park's 3,400 square miles (2.2 million acres) remains undeveloped, providing a wide range of habitat types that support one of the continent's largest and most varied large mammal populations. Yellowstone is a true wilderness, one of the few large, natural areas remaining in the lower 48 states of the United States. Here, you meet nature on its terms, not yours. Park regulations exist for your safety and for the protection of natural and cultural resources. Please obey all park rules and regulations

OPERATING HOURS, SEASONS:
Summer: The season runs from mid-April to late-October.  Once an entrance/road opens it is open 24 hours.  The only exceptions are caused by road construction and weather-caused restrictions.
Winter:  The season runs from mid-December to mid-March.  The road for the North Entrance at Gardiner, MT to the Northeast Entrance at Cooke City, MT is open to wheeled-vehicle use year around.  Only over-snow vehicles are allowed on other park roads.
CLIMATE, RECOMMENDED CLOTHING:
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.
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.
TRANSPORTATION:
To Park: Automobile access is available by many state and federal highways. Commercial airlines serve the following airports year-around: Cody and Jackson, WY; Bozeman and Billings, MT, and Idaho Falls, ID. The West Yellowstone, MT airport is open from June to early September. Other commercial transportation is available seasonally from Cody and Jackson, WY and from Bozeman, MT.
In Park: There is no public transportation provided within the park. Most visitors travel the 370 miles of paved roads in their personal vehicles. Concessionaires provide bus tours in the summer and snow-coach tours in the winter. Please phone (307) 344-7311 for details and reservations.
FEES, COSTS, RATES:
The entrance fee is $20 for a private, non-commercial vehicle; $15 for each snowmobile or motorcycle; or $10 for each visitor entering by foot, bike, ski, etc. This fee provides the visitor with a 7-day entrance permit for both Yellowstone and Grand Teton National Parks. Commercial tours are subject to a separate fee schedule. Golden Age, Eagle, and Access passports are honored and provide free admission to the park.

Details are available on each of these subject areas by viewing our Expanded Website.
 
RESERVATIONS / PERMITS:
Campground / Lodging / Dining - Reservations are strongly recommended for all concession operated facilities. Reservations should be made as far in advance as possible. For reservation information, call (307) 344-7311. For listings, see Facilities and Opportunities above.
Backcountry Camping - Yellowstone has a designated backcountry campsite system, and a permit is required for all overnight stays. Refer to our Expanded Website for more information.
Fishing / Boating - Permits are required. See Fishing or Boating in Recommended Activities/Park Use above.
 
BASIC VISIT RECOMMENDATIONS:
Check at visitor centers for current information on road closures, weather forcasts, ranger-led activites, park regulations, and permits.  Visitors should keep in mind that, due to high levels of visitation, travel through the park can be slow, especially during July and August.  Make lodging and camping reservations as early as possible.   Yellowstone is large and its major scenic attractions are widely dispersed.   You will get more from your visit by limiting your travels to one or two areas if you have one day or less to spend in Yellowstone.  Allow a week or more if you wish to see most major park attractions.
 
VISITOR IMPACTS:
Pets:
Yellowstone National Park is a designated natural area where wildlife is free to roam undisturbed. Even while on a leash, pets are often disturbing to wildlife. For this reason, as well as others, pets are prohibited in the backcountry and on trails and boardwalks. Pets are permitted within 25 feet of roads, parking lots, and campgrounds but must be kept crated, caged or restrained on a leash not to exceed six feet in length.
Other Impacts:
Visitors can unknowingly have a detrimental impact on park resources. Information regarding impacts relating to thermal areas, wildlife, bicycling, and swimming can be found through this link.
 
ADJACENT VISITOR ATTRACTIONS:
Visitor attractions too numerous to mention here exist near park boundaries. Our Expanded Website provides details about many of those attractions.
