Te Ana-au Glow-Worm Caves

The Te Ana-au caves are a culturally and ecologically important system of limestone caves on the western shore of Lake Te Anau, in the southwest of New Zealand. They were re-discovered in 1948 by Lawson Burrows, who found the upper entry after three years of searching, following clues in old Māori legends. It later became a major tourist attraction for the area, as the part of the caverns close to the lake shore is home to glowworms. The unofficial name used by the national caving association is Aurora. The caves are geologically young and hence there is only one tiny stalactite.

The Māori name Te Ana-au can be translated as "The Swirling Cave" in reference to the water running through it. The water, Tunnel Burn, is the outflow of Lake Orbell.
