Caswell Sound Hut
Caswell Sound Hut is a basic four-bunk hut in Fiordland National Park, run by the Department of Conservation. It sits in a small clearing on the north side of the mouth of the Stillwater River, at the head of Caswell Sound (about 500 m from the sound), facing north-west and sheltered from wind coming up the sound.
The hut has a single wooden door and a large fireplace at one end. There’s also a pit latrine on site. Use is free and no bookings are required—it's first come, first served.
The hut is the only remaining physical remnant from the New Zealand–American Fiordland expedition of 1949, built from surplus materials at the end of that project. It was later used as an emergency supply depot for amphibian planes into the area until the 1960s. Access is via Caswell Sound by boat, or (for experienced route-finders) an unmarked route from George Sound to Caswell Sound via Overlander Ridge and Stillwater Valley.
