The final pitch on Comanche is about 500 vertical feet of steep, grassy tundra next to an exposed ridge. Be careful: the marmots are aggressive!
Follow the "Getting There" instructions on the main page for Comanche Peak.
A weak climber's trail begins up the ridge but soon dissipates. Follow this ridge to the summit, or as it gets steep near the top, bear west to bypass the steep section and then east again to gain the summit. The footing is mostly grassy tundra with some large talus blocks - no scree. It is not as steep as it looks from the pass.
No special gear is required in summer. There are numerous snowfields to cross during the approach, prior to July, some of which are a bit steep, so an ice-ax and gaiters would come in handy for early season. The final approach to the pass also maintains a snowfield, possibly with cornice, through June, with a bit of exposure in the last 100 feet.
