The summit of the pass, being at the tree line, is known for its views in all directions. It is also a key departure point for mountaineering; to the north, the gentle ridge of the Sahale arm leads up Sahale Mountain to the summit, as well as to the meadows of Boston Basin and the summits above. To the south, Mixup Arm leads to Mixup Peak and Magic Mountain, as well as to Cache Col, making Cascade Pass the start of the high-level Ptarmigan Traverse.
