Though it ascends 900 feet, CO Rd 176 (aka West Ridge) is spread over 3 miles and is never terribly difficult. There are several steep parts, but then it has many sections of rolling terrain which keep your mood up as you climb higher and higher.
There are many branch roads, but they're all obviously abandoned and it's easy to follow the main road.
Assuming you're heading for the CO Trail Connector
(to get to the CO Trail), keep a sharp eye out near the top of the ridge. Turn right at a switchback and search for an area that looks like a camping spot. There you should find unmarked singletrack heading out. It's very easy to miss this turn, use the MTB Project MTB Project mobile app
! If you miss it, you'll only go a quarter mile more before the road splits, then ends.
