After you climb the 3600 vertical feet up avalanche peak, you're greeted by two spectacles: Crow Glacier
and perhaps 30 highly-entertaining kea. The kea is an intelligent and curious mountain parrot, and they've definitely figured out that it's in their interest to visit the top of the mountain at lunch time, when all the hikers stop to eat. They will definitely take any food (or perhaps rubber) that you leave unattended, using a very loose definition of "unattended". As long as they only try to nibble your boots, though, they're very entertaining.
