A quick, easy, smooth trail. Good for testing out new tires or pedals, but not great for pounding out a lot of miles. You can use this to connect to Dowdy Draw, Community Ditch, Greenbelt, and all of the other trails around this area, though, for a longer ride. I prefer riding this one counterclockwise, but either way is nice. There are a lot of really nice views of the Flatirons throughout the trail, so it's a pleasant ride.
From Boulder, head south on 93. After you pass Highway 128, turn right into the trailhead parking lot (if your vehicle isn't registered in Boulder county, you're supposed to pay a fee; ignore at your own risk!). You can also take 93 north out of Golden to get here.
