When does Yellowstone Open?

Generally speaking, the Park is open throughout the twelve months of the year. But during Fall, Spring, and Winter, access to some locations of the Park is restricted. This is due to heavy snowfall during the winter.

Spring Season

During the spring, some of the park roads and attractions are open for visitors depending on the weather. In late April, roads from West Entrance to Madison are open for vehicles. Travel is permitted between Mammoth and Old Faithful, and Norris to Canyon is also available depending on the weather.

Most passes and roads open from the middle of May, as the roads clear up.

Winter Season

Winter is the season when most areas of the Yellowstone National Park are covered with snow. Guided snowmobile and snow coach tours take place this season, you may check out the NPS website for more information on winter activities.

The road that connects the North and Northeast Entrances is the only road open during the winter.

Yellowstone National Park employs a full time road crew that clears the roads of snow in the late winter and spring.

Fall Season

Roads in Yellowstone start closing as the weather deteriorates in October. The Dunraven Pass and Beartooth Highway are closed to traffic by this time. By the beginning of November, all the roads and attractions in the Yellowstone National Park are locked except the road that connects the North and Northeast Entrance.


Summer is the best season to make your trip to Yellowstone as all the attractions and roads are open. Occasional closings like accidents or road construction can occur, but generally, everything in the Park is running.

Campgrounds and Lodges

Except for Mammoth Campground, which is open throughout the year, all the campgrounds in Yellowstone are open in the summer. Some campgrounds are available from the start of May, but some may open as late as June. The campgrounds stay open till October. When it comes to lodges, all lodges open in the summer season except Old Faithful Snow Lodge and the Mammoth Hot Springs Hotel, which remain open all year.

When Will Yellowstone Erupt

Yellowstone is often referred to as “the restless giant”. Nobody knows for sure if it will erupt in our lifetimes or not, but we can dig deeper into the structure and properties of Yellowstone.

Inside Yellowstone National Park

Due to the convection of heat in the earth’s mantle below the Yellowstone, magma that consists of molten rock buried under the crust is relatively close to the surface of the Yellowstone. The magma below Yellowstone is caused by the magma pumped towards the earth’s crust from the mantle in the form of narrow streams. This melts the rocks in the earth’s crust close to the surface of the Yellowstone, resulting in the formation of pockets of partially molten and partially solid magma. There are two such pockets of magma very near the Yellowstone surface. Altogether, Yellowstone has two domes and three calderas.

Past Eruptions of the Yellowstone

The earliest estimated eruption occurred about 2.1 million years ago in the Yellowstone area. This was one of the most powerful volcanic eruptions discovered by human beings. As the magma in the chambers was forced up the earth’s crust due to high pressure, tons of magma were propelled out of the land into the Yellowstone vicinity.

Another eruption of Yellowstone is estimated to have occurred about 1.3 million years from today. Magma forced its way above the earth’s surface from the first caldera of the Yellowstone.

The third and latest volcanic eruption occurred in Yellowstone about 0.6 million years ago. This resulted in the present-day Yellowstone Caldera measuring 45 miles in length and 30 miles in width.

Present Conditions and Chances of Eruption

Deformation in the surface and crust has been observed at a large scale between the White Lake and the geyser of Old Faithful. These changes have been observed in recorded history. Many surveys were started during the mid-1970s to record changes in the ground in and around the Yellowstone. Vertical motion surveys were used to analyze the environment and the changes that were occurring if any. By the mid-1980s, vast uplifts of about 3 meters were recorded on the Yellowstone Caldera. These uplifts and subsidies have been recorded since uplifts reduce the pressure of magma. Chances of any recent volcanic eruption are few during the present day, but the possibility of an explosion cannot be ruled out. On the contrary, small lava flows are more likely to occur.

Location of Yellowstone

Yellowstone is located in the remarkable Northwestern United States. It covers a staggering landmass of 3472 square miles and is scattered across three states: Wyoming, Montana and Idaho.

The Park is officially a part of the state of Wyoming as the vast majority of its area, about 96%, is in the form of Wyoming.

The Park touches the northern part of Montana, and about 3% of its landmass is situated there. A small portion of the Park is in the west of Idaho, but it is only a meagre 1% or about 34 square miles.

Important Locations Within and Around Yellowstone

Mammoth Hot Springs, Tower-Roosevelt, Canyon Village, Old Faithful, and Madison have developed attractions. Popular wild areas include the valleys of Hayden and Lamar, which have a great diversity of wild animals to be explored.

At an elevation of 8000 feet above sea level, the Park is situated on the Yellowstone Plateau. From all the sides, the Park is surrounded by giant peaks of the Middle Rocky Mountains. About 5% of the landmass of Yellowstone is covered with water bodies, Yellowstone Lake and Yellowstone River being the most popular.

Creation as a National Park

In the late 1800s, Yellowstone was looked upon by giant corporations and private firms for development. Tremendous and ambitious returning expeditions became a hurdle in converting this marvelous natural wonder from becoming a factory that used human greed as fuel and produced destruction to the natural beauty of Yellowstone. Through the efforts of different expeditions that portrayed the beauty of Yellowstone in their photos, sketches, and paintings, Congress took action and designated the Yellowstone area as a national park. Then-President Ulysses S. Grant, on 1st March 1872, signed the Yellowstone National Park Act, and it became a law. This led to the birth of Yellowstone National Park.

In 1922, opening Yellowstone National Park roads in spring for car travel was a bit different than it is today. This ranger crew shoveled by hand (at least partially) to clear snow from the Mammoth to Norris road through Swan Lake Flats.

Entrances to The Yellowstone National Park

There are a total of five entrances to the Yellowstone National Park. North Entrance is open year-round and leads you to the famous Mammoth Hot Springs. This Entrance is situated in the bustling town of Gardiner, Mont. This Entrance also brings you to the great Lamar Valley, the heaven of wildlife, for the wildlife explorers that venture there. In the east of this Entrance is the Northeast Entrance that is situated near the famed Cooke City. This Entrance also leads you to the Lamar Valley. The Entrance is closed in winter due to weather conditions. East Entrance is the gateway to the splendid Yellowstone Lake, situated at an astonishing height of 7733 feet above sea level. Geothermal features surround this lake at its shores. South Entrance is the best option to explore Grand Trenton National Park along with Yellowstone. West Entrance takes you to hundreds of geysers in the Yellowstone National park.

Wildlife in Yellowstone

Yellowstone is one of the most diverse areas of the United States regarding wild animals, Animals of all sizes and types, predators and prey, and habitats in the wild areas of Yellowstone. Herbivores such as Bighorn Sheep, Bison, Elk, Moose, Mountain Goats, Pronghorns, and Deer are abundant. Predatory mammals such as Grizzly Bears, Black Bears, Mountain Lions, Wolverines, Coyotes, and Canada Lynx are also found in Yellowstone in large numbers. Other than that, smaller predators also call Yellowstone their home and are necessary for the ecosystem of the Yellowstone area. These include Badger (burrowing predator), Cougar, Bobcat, Long-Tailed Weasel, and Marten habitat. The beautiful Park can be an excellent sight for tourists looking for wildlife.


Yellowstone National Park is a major attraction in the Northwestern United States, and one of the top 3 National Parks in America. The Park has a massive land area that expands into three states. The United States Government decided to turn Yellowstone into a national park in the early 1870s due to the efforts of expeditions and artists that explored the Yellowstone area. Thanks to those steps, the incredible biodiversity of the Yellowstone area prevails to this day with dozens of predatory and prey species.
