Te Anau Glowworm Caves
Southland
The Te Anau Glowworm Caves, also known as Te Ana-au Caves, are a significant natural and cultural landmark located on the western shore of Lake Te Anau in New Zealand's Southland region. These limestone caves, estimated to be around 12,000 years old, feature a unique ecosystem highlighted by glowworms that illuminate the caverns near the lake shore. The caves are named 'Te Ana-au,' meaning 'The Swirling Cave' in Māori, referring to the swirling water of Tunnel Burn flowing through them. Rediscovered in 1948 by Lawson Burrows, the caves have since become a popular tourist attraction, with guided tours operated by RealNZ offering visitors a scenic boat ride through the water-filled passages. Due to their fragile environment and ecological importance, access is carefully controlled to preserve the caves and their inhabitants. The experience includes a scenic cruise across Lake Te Anau, a guided walk through the cave, and the chance to witness the glowworms in near-complete darkness, creating a magical natural light display. Visitors are advised to wear warm clothing and non-slip footwear, as temperatures inside the cave remain cool year-round. Photography inside the caves is prohibited to protect the delicate glowworms and enhance visitor experience. The caves' proximity to the Fiordland rainforest and their connection to Māori legends add cultural depth to this natural wonder.

History
The Te Ana-au Caves were rediscovered in 1948 by Lawson Burrows after following clues from Māori legends.
The caves are geologically young, formed approximately 12,000 years ago, and contain only one small stalactite due to their youth.
Initially developed for tourism by Burrows and Wilson Campbell, the business was sold in 1965 to Olive and Les Hutchins, who continued promoting the site.
The tourism company underwent rebranding from Fiordland Travels to Real Journeys and later to RealNZ.
The caves lie within the Murchison Mountains, an area known for the rediscovery of the endangered South Island takahē bird, highlighting the ecological significance of the region.
Access to the caves remains restricted to protect their fragile environment and unique glowworm population.
