The Muir Wall is a major El Capitan big-wall route and a classic aid climb. It is long, steep, and committing, with sustained technical sections on granite. The route is typically climbed over several days and requires wall-climbing systems, hauling, and bivouac capability. It is well documented in Yosemite climbing sources and guidebooks. The climb is exposed to rockfall and weather, and route-finding can be complex. It is a technical rock ascent rather than a hiking or scrambling route.
