Te Anau is a small town on the eastern shore of Lake Te Anau, the gateway to Fiordland National Park and one of the most spectacular wilderness areas in New Zealand. It sits roughly halfway between Queenstown and Milford Sound, about two hours' drive from each.
The town is the departure point for the Milford Track, one of the world's great walks, and also for the Kepler Track, which loops through beech forest and alpine tundra right from the edge of town. Day cruises to Milford Sound and Doubtful Sound are booked from here, and the Te Anau Glowworm Caves across the lake are worth an evening visit.
Te Anau is the last town with full services before Milford Sound — there are no petrol stations, shops, or accommodation on the 120 km road between the two. Fill up here before heading into the fiords.
