  • Description 

    This area includes popular and classic rocks such as the First and Third Flatirons, and the Amphitheatre in Gregory Canyon. Climbs here range from short newer-age sport climbs to long, trad, slab routes, including some of the longer trad routes in the Flatirons: the whole face of the 3rd, which is about 1300 feet and the Direct East Face of the First Flatiron which is about 1400 feet. Hard conglomerate Fountain Formation sandstone is the medium for your rock craft.

    Getting There 

    The usual approach to most routes in the North Flatirons area is from Chataqua Park (which can be crowded) or Gregory Canyon Trailhead (which charges parking fees for non-Boulder County registered vehicles). Take Baseline W. until you see a sign for the park on the left (you can't miss it since it's right below the Flatirons). For the Amphitheatre, continue on Baseline past the park entrance until Baseline curves sharply right up Flagstaff Mtn. Park on the road near here, or on the turn off to the trailhead on the left. You MUST pay for parking at the Gregory Canyon lot if you do not have Boulder County registration or you'll be ticketed by the Man.


    Various of the Flatirons are closed for falcon nesting from Feb 1 up to July 31 and for bat nesting Apr 1 to Aug 31. Historically, some of these in this area have included Sacred Cliffs, East & West Ironing Boards, The Third Flatiron, Queen Anne's Head, occasionally Gregory Amphitheatre, and possibly others.

    It's definitely the longest runout I've seen on a 5.7

    If you're like me, the rating scale for slab climbs is different than vertical crack climbs. In other words, a 5.7s Flatiron and Eldo climb are very different in nature. You won't notice a 80ft. runout on the Third like you would on a climb like Icarus (5.6s) in Eldo. With that said, be wary, but not scared off by the serious fall potential rating.Start from the East Bench and move straight up. You may also move to the L and belay at a small tree on the edge of the channel. After three pitches, ...[more]   Browse More Classics in CO

    Great climbing area, but probably not the best place to go when CU has a home game. Trying to get out of there along with all of the football fans is way epic.
