Panorama Point on Flagstaff Mountain in Boulder, CO, offers stunning, panoramic views of the city, whether it's day or night, all year round. You can drive up to the overlook, making it accessible to families and dogs. Parking is limited, however, and the vehicle length limit on Flagstaff Road is 30 feet because it is narrow and twisty. Several trails start and/or pass by here including Flagstaff Trail and the Viewpoint Trail, the latter of which climbs from Boulder Canyon and Eben G. Fine Park near downtown. Panorama Point has three picnic tables, but no restrooms.

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!
