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.
