I didn't get a chance to explore all of this trail, but I was very impressed with what I saw of if as well as the Denver cycling infrastructure in general (handlebar videos available at youtube.com/ratbas). The idea of being able to ride for miles through a major city without having to cross an intersection is very enjoyable. The trail is well maintained, has good signage and plenty of public are while taking you past many points of interests. There are also countless access points to make it very practical for commuters and tourists.

Nice surface well maintained sidewalk. All exposed no shade. Winds through an industrial area past the power plant. The connection to the trails across Nevada is hidden and hard to find.

Growing up in COS, I had taken many rides on the cog rail train, down was always better than up!
Then I found out years later that the train had closed :-( and they turned it into a trail :-)… it's a walk, and now that I'm from FL-it's a real walk!

This is one of the loveliest and nicely maintained urban bike trail I have ridden. The trail is paved and wide without many hazards on the pavement. The trail is well marked for the most part. I did miss a turn at one point and found myself on a different trail. Eventually, I turned back and found the correct trail again. I had missed the sign on a fork in the road and turned on to the wrong trail. The scenery is very lovely - it follows along a stream with pretty waterfalls.

For a trail bike, this is a short trail for people who don't need nor want a challenge. The only part that gives me trouble is a rutted, steep grade down to the Mesa Creek. Other trail bikers can manage it, but I can't keep my tires in a good track and I end up walking the bike down. :p

There's wildlife to see, a creek, and varied landscapes from large cottonwood and willow stands, to desert hills, and a swamp at its lower end into Sondermann Park.

The trail is listed for foot, bike, and horse usage only. Unfortunately, it is not marked as limited usage nor blocked off from the motorcycle and 4 wheeling tracks that run to the north. Be aware that they sometimes spill onto the this trail.

The Arkansas River section goes 3 miles beyond what TrailLink shows, and the Fort Creek section adds another 5 miles, all excellent concrete surface. See https://www.pueblo.us/314/Pueblo-River-Trail-System for a nice PDF map.

We rode the section from the McCabe Meadows Trail Head to the Cherry Creek Reservoir around 27 miles round trip. Although it's mostly only 8 ft. wide, the trail is in very good shape and has lot's of wooded, prairie and urban sections. It's a mellow ride with very few big inclines! We really appreciated that there were several trail heads with facilities (restrooms, picnic table, etc.). We plan to ride the next section north into Down Town Denver soon, we really enjoyed this trail!

Great trail. I walk my German Sheppard on this trail. You can see all kinds of wild life. Trail is through Housing areas and runs north and south. There are a lot of bicyclists on the trails.

Trail has bikers, walkers and joggers with heavy usage. It's relatively flat and any novice can do it. However be warned, there are numerous bikers who ride at speeds over 20mph (posted limit of 15) and don't care to slowdown for congestion or warn people being overtaken. While every ride is enjoyable, this one was more stressful than any I've been on.
