This is a great advanced ride if you’re looking to get a warm-up on the road. Park at the lower EMT parking lot and ride the road up to Coal Bank Pass. Once you’re at the pass, climb Pass Creek trail up 3 miles, ~950 feet and then descend down Engineer Mountain Trail.
Caution: the road doesn’t have a huge shoulder so you do have to think about traffic and all of the risks or riding on the road exist her. I prefer to start this climb early in the morning before the traffic starts.
