Flatirons Classic Climb

Flatirons Classic Climb

The immense First and Third Flatirons rise over Boulder like unmistakable landmarks signaling the presence of the Rockies. The Flatirons Classic Climb is a discounted guided climb of one of these formations that we offer each week. Depending on the group and time of year, we’ll either climb the 1st or 3rd Flatiron.

We guide all routes on the First and Third Flatirons any day of the year (barring seasonal closures on the Third to protect nesting raptors), but we’ve designed a convenient, economical way for you to experience the most popular routes on these formations throughout the summer.

First Flatiron, Direct East Face An incredible route, following flakes, corners, pronounced edges and excellent friction for 1,000 feet at a modest difficulty of 5.6. The crux of the ten-pitch route comes right off the ground, then easier climbing leads to a spectacular final ridge and an airy summit.

Third Flatiron, Standard East Face Climbing pioneer, and Patagonia owner, Yvon Chouinard, called this route the “finest beginner’s climb in the country.”  One of the most classic routes in all of the front range, this seven pitch route climbs up the center of the Third Flatiron face.  Rated at 5.4 this route is an amazing climb regardless of your climbing ability.
