Note: Described in the reverse direction to your journey

Follow yellow triangles marked MR N (Main Ridge North). Be careful of other traplines going off the side. When you get to the saddle beside 645 take the unmarked bench track. This joins up again with the main ridge track with the yellow triangles later. 200 m from the hut turn south, triangles marked 'hut', then turn right and you'll be at the hut.
