From the Sunrise carpark follow the farm track for 10 minutes to reach the Triple X Hut. This 12 bunk hut with grassy surrounds and space for camping is an ideal base for groups wishing to experience an overnight stay close to a road end.

About 100 metres before the hut is the access point to Swamp Track. This low level track meanders through a mix of beech, rimu and kahikatea forest at the base of Sunrise Track. This track can be completed in a circuit from Triple X Hut.

Triple X Hut and Stream and the Armstrong Saddle all derive their names from a pilot, Hamish Armstrong, who crashed onto the saddle in 1935. The plane wreck was found after several weeks of searching, but Armstrong himself was never traced. A shirt labelled “XXX” was the only clue found to his whereabouts.
