Mt Sydney King

From the Aida Glacier climb north up a snow spur to the col then continue north-east along snow and rock 150m to the summit. Alternatively, climb to the col on the south-east ridge that leads from Acland, then up a rocky ridge to the summit. The Joie de Vivre Buttress, on the north-western side, has also been climbed - this can be accessed from Phyllis.

From the head of the Joie de Vivre Glacier climb to the col south-east of Mt Phyllis then travel north-east along snow and rock to the summit.

Climb the buttress directly to the summit from the Joie de Vivre Glacier.
