South Skybound Watch is a ruined Nordic tower located on the mountain south of Riverwood in the Falkreath Hold region. The tower can be reached by following a path leading from the main road just east of Helgen's eastern gate, or by passing through Skybound Watch Pass from North Skybound Watch.
The tower is mostly destroyed with wooden stairs leading to what remains of the top lookout point. There is a door on the ground floor which leads to Skybound Watch Pass. There may be a Wispmother near the entrance of the tower.
There is a chest at the top of the tower and a light armor helmet on the table on the second floor of the tower.
