The immense First and Third Flatirons rise over Boulder like unmistakable landmarks signaling the presence of the Rockies. They also offer the Flatirons’ best climbing, with over 40 different routes on fantastic quality rock. Most of the actual climbing perfectly suits the beginner and intermediate, thanks to excellent flakes and face holds. But despite moderate difficulty grades, the routes can be serious. They usually involve challenging route finding and long runouts. Our guides have the expertise to safely show you the ultimate Flatirons experience. And once back on the ground and hiking one of the many well-maintained paths back to the trailhead, you’re only minutes from downtown where great food, drink and more earthly entertainment await the end of an exhilarating day. It’s a day you won’t forget.

We guide all routes of the first and third Flatirons any day of the year, but we’ve designed a convenient, economical way for you to experience the most popular route on the First Flatiron every Saturday during the summer.
