This is the starting point to visit the Te Anau Glowworm Caves, offered by RealNZ. You'll take a scenic cruise across Lake Te Anau and then explore the caves with knowledgeable guides, marveling at limestone formations and a stunning glowworm display. The experience also includes a boat ride beneath a canopy of twinkling glowworms.
Note: no pictures are allowed inside the caves. If you're visiting the North Island as well, we'd recommend visiting the Waitomo Caves instead as there are a lot more glowworms!
