The Cassin Route is another major historic line on the north face of Cima Grande and is firmly established in the alpine literature. It is a serious, sustained rock climb with difficult technical passages and a strong alpine character. The route is known for exposure, commitment, and the need for precise route-finding on steep limestone. It is generally climbed by experienced alpinists in stable weather and dry conditions. As with the other north-face routes, rockfall and changing conditions are important hazards. The descent is typically made via an established descent route after the summit.
