What's the best bike path in Denver?

I really like the Clear Creek trail from Golden to the Platte River trail. If you want to go even farther, you can then go down the Platte River trail to downtown and beyond.

I'm not an avid biker, but I thoroughly enjoy the Cherry Creek trail. When you get down around LoDo, the trail splits to bikes only on one side of the creek, and pedestrians only on the other side of the creek, which is a good idea. There have been times where there's something going on in Larimer Square, like the Chalk Art Festival, and there are so many bikes and pedestrians it's crazy! What awesome though, is that you can ride from Downtown Denver all the way to Cherry Creek Reservoir. It's a beautiful ride.
