Visitor Reviews of Aoraki-Mt Cook
- Peter Taylor from New Zealand writes:
Generally a well-serviced mountain, featuring excellent coffee at Plateau Hut. Service at Empress Hut is a little slow, and, apart from a peculiar rocky pudding, non-existent at Gardiner Hut. Queues on popular blue run the Linda tend to get very long in January and there have been some instances of fisticuffs amongst impatient punters at Summit Rocks. The Nor'West Ridge is a somewhat less crowded blue run, but it's a long walk from the hut with no guarantee of good conditions from the summit. The public are warned to exercise caution on descents of the double diamond Hooker Face as it can get a little hard and slippery at times. Late season, often as early as mid-January, there are excellent natural terrain park features on the lower Linda.
