Along a railroad track most of the way. This it is a steady incline. The trail is smooth, so instead of looking at the path the entire time, you can look around and enjoy the views. A good number of hikers, but everyone was friendly.

Lovely trail! Very well marked. Amazing views even though it is mostly flat! There are some inclines for sure but not difficult at all. Highly recommend and I will absolutely do again!

Very nice hike, there was snow on the ground so kind of slushy coming down, but great views of the lakes and the cave was really neat, not too crowded and plenty of parking when we got there around 11am on a Saturday

The trail was great. The views on the top-amazing! The only negative thing was the 4mile dirt road to the road starting point, especially for a small VW Jetta. We got there around 9AM and only saw one other group of people while hiking up. Expect snowy, icy, slushy, rocky and sandy terrain

Since we started around 11am, the snow was melting into slush and small creeks on the trail. We almost missed two turnoffs but thanks to earlier footprints in the snow we quickly corrected ourselves.

Very easy trail, small elevation gain, interesting tunnel and beautiful lakes. Many people in the trail and 4WD road to trailhead.

HikingGreat!

The access road to the trailhead was... uncomfortable, but manageable in my small SUV. In a couple of places, a smaller car would struggle. On the road to the trailhead, you will pass a parking lot on a switchback with two other trailheads, but keep driving for this one. There is another small parking area further along with enough space for 20-25 cars. When we arrived at 11:30 on a Saturday, there were still plenty of spaces available. The trailhead sign reads 'Colorado Midland Centennial Trail' and a length of 5.5 miles. If you're here, you're in the right place. The hike is very enjoyable and manageable for inexperienced hikers and dogs. Two small lakes, remnants of a deserted railroad 'city,' a glimpse into an old, snow-filled mountain pass tunnel, and scenic mountain vistas can all be seen if you complete the full loop trail. My recommendation would be to take a right when you get to the start of the loop. This is "backwards" from the way the hike is usually done, but we preferred it. This puts the most memorable views at the second half of the hike, and the quicker elevation changes downward.

Great trail! Interesting history, beautiful wildfires in mid August, and two lakes. The loop begins always in. Drive in was fine; just go slow.

The lakes were beautiful. The views on the whole hike were great. The road is not bad. A passenger car was at the trailhead. The sign at the Trailhead says Colorado Midland

This is our favorite trail in this area! There is not a spot on this trail that doesn’t have a beautiful viewpoint of lakes, mountains and/or wildflowers. The trail is pretty easy going as well, given that most of it is on old railroad beds. This is a six/seven star trail (on the five star scale).

Nice trail with lots of history. The tunnel was cool with ice in it and reading about the lives of those who built the rail bed and tunnel was interesting. Beautiful scenery all along the way. Could definitely use some signage to guide you. When we reached the intersection of 4 trails we continued to the right following the old rail bed. It’s washed out at one point but the detour trail is easy to spot. After leaving the tunnel we took the first right to complete the loop and pass through Douglass City. Stopped for lunch at the second lake below the tunnel. Lots of wildflowers. Road to the trailhead is rough but doable. Passed beautiful Turquoise Lake on the way. Enjoy!!

Great trail! Steady gradual incline. Beautiful views from the top. Family friendly. Only moderate traffic on the way up and down. I'd definitely do it again.

Did the trail last August 2019 and forgot to review it. Since I can’t speak to current conditions, I just want to say this hike is a family favorite in the Leadville area, though the drive up to the trailhead is a bit harrowing if you’re not used to narrow, curvy dirt roads with steep drop-offs. (Made it in a Corolla no problem, though.) Also—don’t go in the tunnel. Seriously. I met some retired mining geologists there who did go in, then noticed a crack that they said was “troubling,” and which might have made them change their minds had they noticed before going in!

HikingGreat!

Look for the Colorado Midland sign at the parking lot at the start of the trail. Be sure and stop and read the description of the history of the trail and the Midland railroad. Flowers were spectacular today. We started our hike right after 9 AM and I only saw a couple of people along the way. Saw lots more on the return trip. Be aware the signage is not good. About 1 1/2 miles in from the trail head there are several possible ways to go. You’ll want to turn and go up the hill to your right or you might wind up going down to the Windsor Lake trailhead. You’ll hike through the ruins of Douglas City and there is a sign there discussing the history. You’ll also see evidence of a railroad trestle before arriving at the tunnel. Great views. We enjoyed the wildflowers.
