FATMAP difficulty grade
Mt Philistine is an excellent early mountaineering outing in Arthur's Pass, moderately wild.
The crux is at Warnock's bluffs.
After crossing the Otira footbridge, ascend scree to the shoulder of the Warnock bluffs spur, then sidle round a little to gain an easy gully scramble.
Don't be tempted to scramble up rocky tussocks too early, the route up should be fairly easy scrambling up a faint track.
Above, follow the broad gully towards the summit.
Return the same way.
