The views from here are amazing. It shows just how wide and open Davidson Mesa Open Space is. It's a great place to stop for a pause.

Sunshine Canyon is a popular ride that that takes you straight from downtown Boulder up into the foothills past popular hikes like Mount Sanitas and Lions Lair. This upper section of Sunshine Canyon is gravel, but it is generally well-graded, and hard packed; it is frequently completed by local cyclists on road bikes. The only place where the gravel can be a little looser and chunkier is toward the top of the canyon by Gold Hill, so be aware when ascending or descending.

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!
