Wanaka is my favourite NZ place. And I will be back there 8-15 August so look forward to ski at Treble Cone and Cardrona again! And I agree about the view from Treble. Also climb up to the summit rocks from the top of Saddle Lift and the view from there is out of the world! as for getting there for sunrise, well, I am not an early riser 🙂
