Any combination of U.S. 12, U.S. 191, U.S. 87, and I–90 will make a quick route to Billings. However, if you have the time, try getting off the main roads. The square of beautiful country between these four highways is the location of Halfbreed Lake National Wildlife Refuge, part of the Charles M. Russell National Wildlife Refuge. The several thousand acres of Halfbreed encompass a seasonally wet lake and wetlands, creeks, and grassy plains. Wildlife includes grouse,
waterfowl, grasslands birds, deer, and antelope. This is a favorite spot for birders.
