How to Reach Yellowstone in 1920

Adapted from the official 1920 guidebook to Yellowstone National Park.

In the summer of 1920, America's first national park was already a global marvel—but reaching it was a journey through the backbone of the continent. Trains, stagecoaches, and the early automobile brought adventurers from every state to the wilds of Wyoming, Montana, and Idaho.

Rail Routes to the Park

Travelers had multiple options to access Yellowstone by rail:

  • Northern Pacific Railroad brought visitors to Gardiner, Montana—the northern gateway to Mammoth Hot Springs.
  • Union Pacific (Oregon Short Line) carried travelers to West Yellowstone, Montana—the western entrance.
  • Chicago, Burlington & Quincy Railroad offered service to Cody, Wyoming—gateway to the eastern entrance.

From these terminals, travelers connected to Yellowstone’s interior via auto stages or horse-drawn transport operated by licensed concessioners.

Entering by Automobile

By 1920, Yellowstone was fully open to automobile traffic—but under strict regulation. Motorists paid a $7.50 entry fee and had to follow directional rules designed to maintain order on the park’s narrow roads. Speeds were limited to:

  • 20 mph on straight roads
  • 12 mph on uphill grades
  • 10 mph downhill
  • 8 mph near animals or curves

Permits were issued at entrances and required display upon exit. Vehicles had to carry extra tires, lights for night travel, and pass inspection for brakes and engine condition.

Conditions and Warnings

The 1920 guide cautioned that Yellowstone’s high altitude—averaging 7,000 feet—reduced engine power and increased gasoline use by up to 50%. Drivers were also warned about overheating on long mountain climbs.

Motorcycles were not allowed in the park at all. Horse-drawn vehicles had priority over cars, and all vehicles were expected to yield to saddle horses and wildlife.

A Gateway to Wonder

Whether by rail or by road, the journey to Yellowstone in 1920 was as much a part of the adventure as the park itself. Visitors came to witness the geysers, breathe mountain air, and step back in time—to a place that even then felt sacred and untouched.
