Tyndall Gorge is comprised of the alpine rock routes on Hallett Peak, rock and alpine routes on the south face of Flattop Mountain (The Dragon's Tail), and Emerald Lake bouldering. Easy access from Bear Lake increases its popularity (let's play Dodge the Tourist!), not to mention some stellar routes. The area has something for everyone - easy alpine cruises, long trad routes, hard ice climbing, and boulders.
From the Bear Lake Trailhead, follow signs to Dream Lake and Emerald Lake. A 45 minute hike up the canyon on good trails gets you to the upper-most lake - Emerald Lake. The alpine routes and rock climbs on Flattop Mtn. are accesses by rock hopping around the north side of the lake. Hallet Peak is reached by traversing the slope above the south shore. Allow an hour to the base of Dragon's Tail Couloir (in the summer) and an hour and a half or more to the base of Hallett.
