There are two great spots that I would suggest to see the Oregon Trail. One is Blue Mountain Crossing, just off I-84, about nine miles west of La Grande. It’s a half-mile paved, easy accessible trail that follows some of the best preserved and most scenic traces of the Oregon Trails. Blue Mountain Crossing has discovery trails where you can literally walk in the footsteps of the pioneers. Plus, there are benches and picnic tables where you can rest.
The second spot I suggest is the National Historic Oregon Trail Interpretive Center in Baker City. This is a great museum that offers you with a hike out to see the wagon ruts. Managed by the BLM, the center tells the story of emigrants through exhibits, program, films and special events. Specifically, the center focuses on six themes related to westward migration and settlement: pioneer life on the Oregon Trail, mountain men and early trail travelers, Native Americans along the Oregon Trail, natural history along the trail and in Eastern Oregon, mining and early settlement, and the history of the general land office.
