The col is reached via a straightforward ascent from the upper McCoy Stream. To reach the Rakaia River, climb around Pt 2091 metres to reach the couloir immediately south of the point, and then follow this couloir down to Kirk Stream. From here, do not descend Kirk Stream. Instead, climb to a small saddle south of Prelude Peak, head east, and follow the spur that leads down from Pt 1753 metres to reach the upper Rakaia River at the east end of Lyell Lake.
From the head of Kirk Stream the col is a straightforward climb up a couloir immediately south of Pt 2091 metres. From here follow the ridge to the col.
