The Ashton-Tetonia Trail was once the path of the Teton Valley Branch of the Union Pacific Railroad between Tetonia and Ashton. Nowdays it connects the city through a well-maintained trail administered by the Idaho Department of Parks and Recreation and is managed through Harriman State Park. It passes by old trail stations, over three historic bridges, winding through small riparian riparian areas, with amazing views of the mountains.

Scenic and teaming with wildlife Harriman State Park's Silver lake is a great place to ride on your way to/from Yellowstone. Or, you could stay for a while and avoid the crowds of the more famous neighbor while still have an incredible outdoor experience.
