Brainard Lake is a beautiful alpine lake in the Indian Peaks Wilderness below the Continental Divide surrounded by subalpine forest. It is in the Brainard Lake Recreation Area, which during the summer season usually requires a reservation and a fee, but if you are on your bike you do not need to pay or reserve a time slot. Because of the area's high elevation, snow typically remains until late spring, even on the paved road to the lake.

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!
