Pigeon Island is a small island at the Glenorchy end of Lake Wakatipu. You can only get there by boat/kayak, (unless you’re a really good swimmer!) There’s a handful of short tracks on the island, and when we visited we climbed to the island’s high point for good views over the grand peaks at that end of the lake. There are also plentiful weka there, an otherwise rare flightless bird confined to just a few islands in New Zealand.
The walk starts at the island’s camp ground, and is a shortish climb up about 150 vertical metres.
