The trail is an old railroad bed with some double track, but mostly single track with some railroad cuts that have collapsed and tressels that have rotted away making portions of the trail more challenging.

Beautiful views on the trail. however it's not a very well marked out trail by any means. Trailhead nor route is clearly marked and we briefly wandered off trail multiple times.
Not a very strenuous hike by any means.

Beautiful! Great views! Very highly recommended! (Bring bug spray. Tip: Get close to the mouth of the tunnel and the mosquitoes won't bother you. It's the best spot to take a break up there.)

Low traffic. Great place to get away.

GREAT trail. Not to strenuous but still a decent slope. The tunnel at the top is defiantly the highlight of the hike. Two great lakes. Make sure to bring bug spray.

Great trail nice having a destination like the Tunnel and the old town! I really enjoyed this hike with my dog and would recommend this trail to anyone wanting a short out and back hike in the Leadville area.

Only a few more strenuous spots, this isn't a terribly tough hike. What's amazing is the mining and railroad history in which this trail is built. Even more amazing is how quickly the entire place was abandoned after the railroad was finished.

Take the short drive past the lower tunnel to skip a not particularly interesting extra mile. The trailhead for hiking is less prominent than the Jeep trail up to Hagerman Pass, so make sure you're heading the right way. The hiking trail heads into the woods while the Jeeps drive up a rocky path.

Firstly, we drove to the 4WD trailhead in a tiny 2WD car. It was pretty much as good a road as the 2WD dirt road to the lower tunnel. A couple questionably large rocks that can be avoided with slow driving. Late June and the trail is nearly impassable at a couple points due to extremely fast moving and eroding streams. I had to carry the medium dog across one or two of them that went up to my mid-calf. One of them has eroded the trail so badly there's barely enough horizontal surface to walk through. But we got past it. Then we get to an intersection and a sign saying simply 'trail'. Contrary to my belief that the cross trail was the important trail it seems to only mean you are already on the trail. So don't listen to the sign and just keep on with what you're doing. (but do follow the lined up rocks earlier that direct you) We saw Douglas City instead of the tunnel because the sign confused us and then it was too late to go back. The views here were amazing. Huge peaks in all directions. Lots of ruins including remnants of a brick structure almost as far up as you can go. We could see the tunnel above us. There was a serene and pretty little lake. On the way down we tried to figure out how to come out at lower tunnel parking area so we could avoid all those crazy streams on the trail but snow fields obscured the barely visible alternate trail so it was a struggle to get down. By the time we did we were very happy to walk up the dirt road to the trailhead parking lot.

Nice trail with great views with the added interest of the tunnel. Your not able to enter the tunnel but just a few feet. Trail was varied from single track to double to rocky scramble where some of the cuts in the rock have collapsed. I hiked the trail doing the cutoff through the old town site and looped back through the full hagerman route. The total miles was 7.1.

We had a lot of fun with this hike. Some neat railroad history here that you'll see along the way. The tunnel at the top is interesting as well. I can't imagine what it took to put a railroad tunnel through the top of the mountain...let alone get the train to this elevation! And....it was used for such a short amount of time!

We did this as a loop, taking the railroad grade back down the mountain. Don't forget your camera!
