If you expand the above photo, you will see a snow-capped mountain at the far end of the lake. This is the highest mountain in New Zealand, for more details refer to the wikipedia entry here. The Hermitage Hotel in the Edmund Hilary Centre offers simple and fresh lunch in a canteen style. Best of all, you can enjoy the view while you grab a quick bite. But it's not such a good idea to climb up and see the Hooker Glacier though. It's a tough climb on a hot day and you don't see an awful lot.
