A few weeks ago a neighbor introduced me to a local trail, that used to be an old railroad bed with tunnels, just outside Manitou Springs, Colorado. There's no official trail head or even any indication of where to begin from the road. We drove about 2 miles up the Hwy 24 pass and doubled back just a bit. It's actually just across from Waldo Canyon Loop.
The first leg of the trail was rough going. Steep and rocky with lots of loose dirt thrown in. Good traction required! I was thinking (okay, worried) about the way down later on...
Once on level ground I found the views amazing and the trail very pleasant. Wasn't far before we were no longer following the highway pass (and the noise), but walking along a quiet railroad bed.
The two photos with the views are taken standing at the outside entrance, looking in. We passed through four or five tunnels and only needed flashlights in the last one, which was in almost total darkness. We notice that the tunnel was impassable beyond that point.
The way down wasn't quite as bad as I expected it to be. I found more information about the Midland Railroad Trail after returning home. The beauty of the web!
This little river stream is just down the road, driving East toward Manitou, in a pull out section. Nice spot to end a hike!
