Fun, easy hike up to an old mining town. Mostly flat and wide so you could bike it or bring a stroller but you'd defintely have to carry either for some rocky/hilly stretches.
Some neat artifacts if you're into trains and old homesteads. Be sure to pass the old lodge and red cabins & train turntable (across the other bridge) to hike up to what used to be Dumas Street. The preservation society has done a nice job with the photos/info to help you imagine what the old mining town looked like.
