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

Amazing views ant the tunnel is spectacular. We found the road quite acceptable and there was no need for parking earlier. We drove a small suv, but with some care any car can reach it with no problem. This IS a dirt road so rain/snow can make things much more challenging quickly. Hike itself was beautiful, mostly very easy with some minor challenges. Very quiet, very wonderful.

We hiked this on 10.05 and the aspens were gorgeous. This is a great, easy trail. The road to the trailhead was driveable but we heeded some other's reviews and parked at the Windsor trailhead, walked up the road and missed the Hagerman Tunnel sign...it's a wooden sign but for some reason it didn't seem obvious to us and we walked past it another mile. once we found the trail it was an easy hike. We went cw up to the tunnel which was really cool. I didn't go in very far. Since we're parked at the Windsor trailhead we took that trail back to our car which saved 2 miles.

If you only have a 2 wheel drive car I would recommend starting at the Windsor Lake trail head and not driving up Hergman Pass. Gets pretty sketchy and we ended up backing down after only going past Windsor by 100m. Beautiful hike though. As you head up Windsor there is a trail sign on a tree Windsor to the left and Hergman to the right. We ended up combining both and hitting Windsor first and the. Doing the Hergman loop. Total distance was 6 miles. Amazing views and awesome lakes and ghost town. Highly recommend for a 3-5 hour hike.

We started at the Windsor Lake trailhead and did the loop up to Hagerman Tunnel. Gorgeous, abundant wildflowers everywhere and lots of streams and ponds! The tunnel looks like something out of a fantasy novel...very cool! The first mile or so was pretty steep, but the rest was easy.

Fantastic trail! Easy to moderate climb up to Douglas City, then moderate to difficult to the tunnel. Easy hike down. Beautiful views of wildflowers and the old buildings. The tunnel was worth the hike as it is filled with water and ice. Definitely a must hike!!!

I started at Midland Trail. Which isn’t a choice in AllTrails. But it was a great hike.

This was a beautiful hike, not too difficult either, especially if you're adjusted to the elevation. I may have missed part of the trail, as my hike was tracked to be only 5.8 miles. I went clockwise around the loop, which resulted in slightly steeper uphill at the beginning, and more gradual downhill towards the end, which was easier on the knees. Other than that though The trails grading is pretty level. The loop junction where you'll decide which direction to take can be easy to miss, it's only marked by a small sign with an arrow in the direction of the tunnel which you probably wouldn't even see unless you were coming from the right side, and the path to the counterclockwise direction is blocked with stones. The tunnel was pretty cool as well. It's filled with ice starting at entrance and goes back as far as you can see. There's water underneath the ice, and I didn't care to find out how deep it was. Overall it was a fun and easy hike, highly recommended!

Beautiful trail . Well maintained , the app really helped as the trails are not well marked. Don’t miss the Hageman tunnel full of snow and ice up top!

8/3/19 Beautiful trail! Definitely a favorite! Snow is mostly melted off, but still some small patches around. Some streams to cross, will probably get your shoes a little wet. A couple areas on the path are very muddy, but they are easy to navigate around. Lakes, streams, wildflowers!!! There are ruins from a small ghost town and the tunnel is neat to go see as well! Didn’t venture in as you can tell there are animal tracks in the snow around. Also there were some recently fallen rocks from the ceiling, so probs dangerous. The road up to this path is gravel 1 lane wide with shear drop offs for most of the way! Be careful and drive slowly! Lastly, this trail starts at about 11,300ft and tops out at about 12,000ft. It’s rated as moderate, but know that it might be a little more difficult as it’s at altitude.

Hiked this trail a week ago, highly recommend it, the wildflowers were stunning. It's sites on an old railroad bed so it has a gentle incline.

Beautiful hike, although if you have a fear of heights, the road to the trailhead may scare you since it’s one lane dirt with sheer drop offs in areas. Water crossings and water on some decently long areas of the trail make waterproof shoes necessary, unless you want wet/muddy feet. Scenery is gorgeous and the hike is easy with only rocky sections, but nothing technical. It’s at elevation, so if you aren’t acclimated, you would probably huff and puff. Mosquitoes in a few areas near lakes and tunnel. Only saw two other sets of people on my hike today. When you get about 1.5 miles in from parking area, the trail has rocks blocking it and you will see a trail going down...that’s Windsor Lake trail, it’s a hard right up the mountain to stay on Hagerman Tunnel trail.

Beautiful hike. Started at about 7:15am on a Saturday, and we were the only ones on the trail until about the last half mile on the way back. Lots of water stops and a good amount of shade for pups. The alpine lakes at the top are stunning. Relatively flat trail with not a ton of elevation gain made for a relaxing and enjoyable hike. Be sure to keep an eye out for where the trail cuts up and to the right rather than continuing down to Windsor Lake. Will be back!

Pretty easy trail with lakes and a waterfall. There’s still a lot of snow/water on the trail on the longer side of the loop.

It was a really nice walk up to the tunnel today. There was still quite a bit of snow along the rail grade up top in the shade. Was a ton of fun though. Even did a short glissade into the tunnel opening. Weather was perfect. We saw only three small groups of hikers on he trail.

What an awesome hike, the amount of snow still up there is mind boggling. It's an old rail bed, the still flowers were starting to bloom. We had the threat of serve showers, and only received only a few sprinkles.

A few notes (7/15/2019): At the end of the long straight section that parallels Hagerman Pass Road the onward trail is marked closed - blocked by a tree trunk & rocks. There's a clear trail that turns left and goes downhill. We took that for 5 minutes before realizing it was going down to Windsor Lake. So we backtracked and then saw that the original trail continued via a hairpin switchback to the right leading uphill. The trail was clear up to the lake that's just below the tunnel. From there on it was alternating snow, slush and dry. Continuing clockwise around the loop from the tunnel there were several sections where we were in/on snow for 50-100 yards each. One section of trail was impassable but an alternate path was clearly used by others to get around it. All that said, this is a beautiful hike with historical interest. We were the only people on the trail today - an added bonus!

Nice trail -- and since it is south facing there was very little snow on this trail (compared to Windsor Lake which has a lot of snow for the last 2/3). The Hagerman tunnel has a lot of snow but you can climb into the entrance. The lake had a decent number of dry campsites.

July 6th 2019: Hiked this trail yesterday, did the full loop vs there and back to the tunnel. still some snow left on about 40% of trail. it was warm so it was soft and slushy. Did not need tracks or snowshoes though. You cannot get into the tunnel yet, still too much snow at the entrance. A beautiful hike and trail with lots of spectacular views! There are two gorgeous lakes you can see if you complete the loop.

July 2: We made it to Douglas and the lake today but had to navigate through a lot of snow banks along the rail grade and past the town. Most of the snow was pretty hard and we only post-holed past our knees a few times. We followed the rail grade from the parking area to the town and then bushwhacked a little to get up to the lake. Beautiful and very fascinating area.
