From Dillon you can hike and mountain-bike into the nearby Ruby and Tendoy mountains. Blue-ribbon trout fishing on the Beaverhead River attracts thousands of fly fishermen and anglers year-round. A capital of southwest Montana's ranch country, Dillon began as a cattle- and wool-shipping point between Utah and the goldfields of Montana. From the mid-1860s until the early 1900s cattle and sheep remained the primary cargo shipped out of here on the Union Pacific Railroad.
