First up: This is NOT a beginners trip. This trip is only those with previous mountaineering experience.
The above picture is from when we climbed this route last summer.
Climb Mt Philistine and then traverse ridge to Mt Rolleston, heading up to the summit of the high peak:
"Climbed by traversing the ridge from Mt Philistine (1967m), a very long climb generally on loose rock, with many obstacles. Most gendarmes can be turned on narrow ledges (catwalks). Beware of cornices in winter to late spring. Be prepared for a forced bivy should your start route to either summit be a face climb. Some ropework may be required"
Ice axe and crampons
food & water
good boots that can fit crampons
Gas Money for driver
If you have them you may want to bring harness and rope etc
