Lee Hill Drive is a popular, challenging climb that connects the intersection of Lee Hill with Olde Stage just outside of North Boulder, and Lefthand Canyon. The backside of Lee Hill (the Lefthand Canyon side) is a little nicer for climbing because there is less traffic than on the the Boulder side where there is no shoulder on a series of initial switchbacks. Regardless of which way you go up Lee Hill, coming down the 1,400 foot climb is a real treat after the challenging journey up!

This section of the Cottonwood Trail is a short, but sweet, crushed gravel trail that connects Independence Road to Jay Road. It's a nice, scenic way to avoid some of the busy road crossings on Diagonal Highway while enjoying riding next to a creek and past some open fields. While all of this section of trail is very doable on a road bike, there is a bridge crossing that sometimes has planks loose or missing so be aware of that if you're skinnier tires!
