More ways to explore the area's outdoor wonders
You step onto a polished catamaran at the Luminosa pier as Lake Te Anau opens before you — a broad, glassy surface flanked by steep, forested ridges. The boat slips across cool water, and the western shore draws near: Cavern House, a low building tucked into beech forest where the real descent begins.

History
Māori used Fiordland routes seasonally for food and pounamu; later European explorers and hydrographers mapped the lake and its catchments as pastoral stations and conservation areas developed.
Conservation
Cave ecosystems are fragile — keep to boardwalks, avoid bright lights or touching glowworm threads, and follow operator guidance to minimize impact.

Arrive Early to Check In
