There are several routes on the eastern aspects of Mt Franklin. A high camp at Lake Sally is strongly recommended, under the knoll near its outflow. Under winter conditions the routes can all be fraught by overhanging cornices. Eastern descents from Mt Franklin tend to be very steep but natural anchors are available to abseil directly onto the snowfield.
Lake Sally is at best difficult to approach. Access is from the Otehake River West Branch, either by the ridge and loose, bush-covered slopes south of the stream which drains the lake, or alternatively by ascending slopes on the north side of the same stream and sidling around the base of the East Ridge to reach the lake.
