Disappointment Spur Hut was built in the 1950's out of two standard accommodation modules, to support workers on the Snowy Mountains Scheme. The hut is in a small clearing on the side of Disappointment Spur Trail (aka Aqueduct track). There is a supply of water from the nearby aqueduct and a flat area for camping (no toilet). The hut is made from weatherboard with a flat tin roof, has a timber floor and three windows. There is a bunk bed and a table inside, and a fire circle outside.
