Great photos and report Nick! You've captured the feel of the area so well. And you're not wrong about how lucky you were with the weather. A few years back we only got as far as La Perouse before a front - the "weaker" of two that were forecast - almost literally blew us off the mountain. We retreated just in time. We got snowed on in Margate that afternoon!
I wrote this about getting to the summit of La Perouse:
If you were inclined to celebrate your ascent with a football game, the top of La Perouse would not look out of the question. But the winds that blast here most of the time, and prompted walkers to build a massive (and sheltering) summit cairn, would rule out most forms of football most days of the year. A quick and grateful look towards the indented coast; a peek over the edge towards the classic cirque lakes called Swallows Nest Lakes; an admiring photograph over the striking doleritic Cockscomb; a quick celebratory drink; these would be the best you could ask of La Perouse, even on a good day.
I'm looking forward to the rest of your report!
cheers
Peter
