Check out my hike last year at Upper Salmonberry River trail, part of the same 88 mile rail line, destroyed by the 2007 winter storm.
11/6, Sunday, mostly cloudy, light rain at times. 9 of us hiked Lower Salmonberry River trail for about 4.5 miles in, almost always along the trail track, if not on the track. Surprisingly, this doesn't make it an easy walking.
We walked across a couple of bridges, some detailed sections, but not a lot. You can see fiber optic cables clearly at one of those sections. We passed one big water tank, a yellow tractor, and a long stretch of log cars towards the end of our trip. We saw two houses there. Two guys were sitting in the front porch looking at the train carriages as we walked by. We finished our trip at tunnel 35, where we had lunch. It was raining by then.
We saw a salamander, a mini snake, and many little pink flowers on the way. Autumn leaves graced the hill side and the track.
