West Yellowstone, MT Area

West Yellowstone, Montana, USA

On our “Great Western Circle” Tour we traveled on Interstate 15 from Interstate 80 in Salt Lake City and went north to the Utah / Idaho State Line. We continued north on Interstate 15, in Idaho, to Idaho Falls. Then we traveled northwest from Idaho Falls on US Highway 20 to the Idaho / Montana State Line. On this page, we continue northwest on US-20 in Montana to the City of West Yellowstone on our way to Yellowstone National Park.

A small tip of Montana juts south below Yellowstone National Park in Wyoming and eastern Idaho. Highway 20 is only 20 miles long from the Idaho / Montana state line to the west entrance of Yellowstone. The city of West Yellowstone lies just outside the west gate.
