Although technically, this is a bike path, there are extended sections of singletrack that dart in and out of it with some surprisingly technical spots. For maximum singletrack/pavement ratio, start just south of the Holly intersection and look for the little paths that drop off the pavement towards the river. This place can get really busy so ride friendly!
For people who live in Denver, this is an awesome place to go after work and hone your skills and have some fun, plus you can ride it for all but three or four months of the year. I\'m rating it as a 7 with the caveat that this is the highest rating I could ever give a city ride.
The Cherry Creek Trail is a fairly easy hike, being mostly flat with only a few technical sections. However, one can get in a roughly 14-mile round trip if you do the entire thing (it ends a little ways past Evans/Iliff.) It runs north/south between the bike path and the creek.
Sure, there are better hikes out there, but it's central location makes it a good after work hike and it's ease makes it good to take kids on. There's lots of shade and even a couple of bars that serve food and cold drinks about a block from the trail on Iliff. You'll likely encounter other hikers, trail runners, mountain bikers, and kids playing in the creek, so be alert, because there are a few blind corners.
Directions: Park anywhere legal near Colorado Blvd and the Alameda-Cherry Creek Drive area and head east on the Cherry Creek bike path. Right before you get to the Four Mile House, you'll see a drop-in for the trail to your right.
