The History of Over Snow Travel in Yellowstone

From Snowshoes to Snowmobiles: The History of Winter Travel in Yellowstone

Long before modern snowmobiles carried visitors into Yellowstone National Park, winter travel here demanded endurance, ingenuity, and a deep respect for the landscape.

Heavy snowfall, subzero temperatures, high mountain passes, and miles of remote wilderness made Yellowstone’s interior extremely difficult to reach during the winter. Yet people have traveled through this remarkable landscape for thousands of years—first on foot, and eventually aboard increasingly advanced oversnow vehicles.

Winter Travel Before Yellowstone Became a National Park

The human history of the Yellowstone region stretches back more than 11,000 years. Indigenous peoples hunted, gathered plants, quarried obsidian, conducted ceremonies, and traveled along established routes throughout the area.

The Tukudika—also known as the Mountain Shoshone or Sheep Eaters—were among the Indigenous people who lived in the Greater Yellowstone region. They moved through the mountains on foot, following rivers and streams and traveling between higher and lower elevations as the seasons changed. According to the National Park Service, some Tukudika may have remained in the Yellowstone area throughout the year.

Their ability to live and travel in this demanding landscape reflects an extraordinary knowledge of Yellowstone’s seasons, wildlife, waterways, and natural resources.

The Era of Snowshoes and Skis

Yellowstone became the world’s first national park in 1872, but winter transportation remained extremely limited.

During the U.S. Army’s administration of Yellowstone from 1886 to 1918, soldiers used snowshoes and skis to patrol the park during the winter. Their duties included protecting wildlife, watching for poachers, checking facilities, and traveling between isolated outposts.

These patrols were far from easy. Soldiers sometimes covered as many as 20 miles in a single day on snowshoes. Small backcountry cabins stocked with food and firewood offered shelter along the way, although deep snow occasionally buried the cabins so thoroughly that patrols had to locate and dig them out before they could go inside.

When the National Park Service assumed management of Yellowstone in 1918, park rangers continued many of these winter patrol routes. Rangers commonly traveled in pairs, carrying supplies and relying on their skills, equipment, and knowledge of the country to move safely through the park.

For decades, this was what winter travel in Yellowstone looked like: slow, physically demanding, and largely limited to park employees and a small number of adventurous visitors.

The Arrival of the Snowplane

Following World War II, Americans became increasingly interested in winter recreation. Communities surrounding Yellowstone also began looking for ways to extend tourism beyond the traditional summer season.

Keeping Yellowstone’s roads plowed throughout the winter was considered, but park officials determined that it would be costly, dangerous, and impractical. Many buildings in the park’s interior had not been winterized, and the park’s roads were not designed for continuous winter plowing.

A very different solution soon appeared: the snowplane.

Snowplanes were unusual machines consisting of a small passenger cabin mounted on metal skis and powered by an airplane-style propeller at the rear. They skimmed across snow-covered roads without ever leaving the ground.

In January 1949, 35 visitors entered Yellowstone from West Yellowstone aboard 19 snowplanes. This marked the beginning of organized motorized oversnow tourism in the park.

The snowplane was noisy, adventurous, and unlike almost anything used in Yellowstone before. It also demonstrated that visitors could reach the park’s famous interior without requiring the roads to be plowed for conventional automobiles.

Snowcoaches Bring Warmth to Winter Travel

The next major development arrived in January 1955, when West Yellowstone businessmen Harold Young and Bill Nicholls received permission to operate the first snowcoaches in the park.

Manufactured by Bombardier in Quebec, these large tracked vehicles could carry approximately 10 passengers inside a heated cabin. Compared with open-air travel, snowcoaches offered a warmer and more comfortable way to experience Yellowstone’s winter scenery.

During the 1950s, these early operators transported hundreds of guests into the park each winter. Snowcoaches established a style of winter touring that continues today, allowing groups to travel together while a professional guide interprets the park’s geology, wildlife, and history.

Snowmobiles Transform the Yellowstone Winter

The first visitors riding machines recognizable as predecessors of today’s snowmobiles entered Yellowstone in 1963. These early Polaris “Snow Travelers” used motor-driven tracks to carry riders across the snow.

Their popularity grew quickly. Yellowstone recorded approximately 1,000 oversnow visitors during the winter of 1963–64. Only three winters later, that number had increased to more than 5,000.

Snowmobiles offered something different from the enclosed snowcoach experience. Riders could feel the cold air, smell the forest, and experience the enormous scale of Yellowstone more directly. Places that had once required difficult journeys on skis or snowshoes became accessible to many more people.

In 1968, park officials began formalizing an approach that favored oversnow transportation instead of plowing most of Yellowstone’s interior roads. The National Park Service began grooming snow-covered roads in 1971, providing a smoother surface and encouraging riders to remain on established routes.

That same year, the original Old Faithful Snowlodge opened for its first winter season. Visitors could finally travel into the park, watch Old Faithful erupt against a frozen landscape, and stay overnight in Yellowstone’s interior.

A True Winter Tourism Season Had Begun

Finding a Balance in a National Park As winter visitation increased, so did concerns about noise, air quality, wildlife, and the overall visitor experience.

Over the following decades, winter transportation in Yellowstone became the subject of extensive scientific study, public discussion, legal decisions, and changing management plans. Park managers worked to balance public access with the responsibility to protect Yellowstone’s wildlife, natural soundscape, clean air, and thermal features.

Today, winter snowmobile access inside the park is carefully managed. Commercially guided trips use approved routes and modern machines that meet National Park Service standards. These newer snowmobiles are significantly cleaner and quieter than many of the machines used during the earlier decades of winter tourism.

The technology has changed, but the need to travel thoughtfully through Yellowstone has not.

Experiencing a different Yellowstone winter reveals a side of Yellowstone that summer visitors rarely see.

Snow softens the landscape and quiets the forest. Steam rises from geyser basins into the cold air, coating nearby trees with frost. Bison conserve their energy as they move through deep snow, while coyotes, foxes, elk, swans, and other wildlife stand out against the white surroundings.

Traveling by snowmobile connects today’s visitors with more than half a century of motorized winter exploration—and with a much longer human history of adaptation to Yellowstone’s demanding seasons.

Every journey into the park follows routes shaped by generations of travelers: Indigenous peoples, soldiers, rangers, snowplane operators, snowcoach drivers, snowmobilers, and professional guides.

Become Part of Yellowstone’s Winter Story At Yellowstone Snowmobile Tours, we believe the journey is about more than reaching a destination. It is about understanding the landscape, respecting its wildlife, and experiencing the beauty and power of Yellowstone in winter.

When you travel across a snow-covered road toward a steaming geyser basin or watch bison move quietly through the snow, you are experiencing one of America’s most remarkable winter traditions.

The machines may have changed over the years, but the wonder of entering Yellowstone in winter remains timeless.
