1. Explore the Oregon Trail
La Grande is one of the few towns the Old Oregon Trail runs right through. When you drive along B Ave., you're driving the Oregon Trail! The community of Union sits on an alternate Trail route, and houses the Union County Museum, where you'll find lots of fascinating information about the area's history. For insight into the Oregon Trail experience--and get a close-up look at trail ruts--visit the Oregon Trail Interpretive Park at Blue Mountain Crossing, open during months the trail was passable, April through September.
