Go underground with glowworms in Te Anau


Take a scenic cruise on Fiordland’s Lake Te Anau to discover an underground wonderland.

On the western shore of the lake is a 12,000-year-old cave system, complete with a subterranean river and a display of glowworms that light up the darkness.

The Māori name for glowworms is titiwai, which means ‘light reflected in water,’ and this is exactly what happens in Te Anau as you glide through the glowworm grotto in a small boat. 

Pass under the cave’s huge rock overhang to see the swirling shapes of the limestone rock transformed by relentless water, listen to the roar of an underground waterfall, and learn about the fascinating geology and unique flora of the area.
