The Mungo is a tributary of the Hokitika River. The hut is situated on a terrace between the Mungo River and Park Stream. It is about 15 minutes walk up from the confluence which is about 2hrs above the track turnoff to the Toaroha. These days the wet weather route is not maintained so visiting this hut is not advisable if river levels are up! The upper Mungo swingbridge was pulled out in 2011 and a couple of other walkwires are long gone. The fording of the Brunswick can be tricky at normal fine weather flows but Park Stream & the Mungo River should be ok to ford unless there is lots of snow melt.

The hut is an NZFS 1960's style four bunker built in 1971. The hut doesn't get a lot of use, say 5 or 6 parties walking in a year plus a couple of fly in parties.

There are hot springs down from the hut on the TL of the Mungo only just above the confluence with the Mungo River & Brunswick Creek. On the TL about 10 mins below the junction there is another spring.
