West Yellowstone serves as the main entry point along the western edge of Yellowstone National Park, and it is well equipped to handle visitors. You'll find a wide range of accommodation and dining options as well as grocery stores. It's a good place to resupply for those on the Great Divide Mountain Bike Route.

Commonly referred to as the "Cow Trails," the Highland Glen Nature Preserve has a network of single track and double track trails that are open to biking, running, and hiking. In the winter, this is a cross country ski area. The trails get their nickname from the herd of cows that lives in the preserve. Make sure to always close and latch any gates that you go through!
