Lefthand canyon is located north of Boulder, Colorado and is a local cycling favorite. Named after the Arapahoe tribal leader, Chief Niwot (lefthand) the valley is a scenic ride along Lefthand creek. The road was devastated by floods in 2013 but has since been rebuilt with bike lanes and a smooth road surface. It's a comfortable uphill grade until we get to the turnoff for Lee Hill road. This is a quick climb up and over a ridge. Once over the top, Lee Hill road is a fun and fast descent back to North Boulder.
