This trail is an old train track. The tracks are gone, but the rise it ran along is still there. Benches and restrooms are along the trail with great views of the river, iron trellis bridge, and wildlife. The trail is easy going with only a couple of uphill and downhill parts to pedal harder on. The trail begins in Eureka and ends at Lake Koocanusa. About 7.5 miles each direction on this out-and-back historic and memorial trail.
