Few peaks are as thrilling as Teewinot, which culminates in a summit the shape and size of an upturned bicycle seat. But don't attempt it unless you're comfortable with exposed, can't-fall scrambling, or plan to follow an experienced climber on a rope through one or two technical 20-foot sections of nearly vertical rock.
At Lupine Meadows trailhead, find the unmarked climbers' path heading for Teewinot's 5,600-foot east face. It switchbacks steeply to The Apex through a triangle of forest where black bear sightings are common. Leaving the trees, follow the rough path; when it peters out, good routefinding skills are needed to find the easiest way through the steep rock. Stay right of the central gully, which leads straight up to the summit notch; instead, zigzag to the north end of the summit ridge. There, a few third-class moves put you on top, at 12,325 feet.
