-
A guided tour through the cave system, including time to view the glowworms

Are the glowworm caves in Te Anau worth it?
Yes – the glowworm caves in Te Anau are widely regarded as one of the best glowworm experiences in New Zealand and one of the top Te Anau attractions. For those planning an itinerary that includes a mix of scenic, educational, and low-impact activities, it’s easily one of the most memorable things to do in Te Anau.
The caves are part of a fragile, dynamic ecosystem, and the boat-based tour is designed to minimise disruption while allowing visitors to view the Fiordland glowworms in near-total darkness. This creates an experience that feels both intimate and awe-inspiring.
The tour is also family-friendly and suitable for most ages, making it a good option for those looking to experience Fiordland’s unique geology without embarking on a long hike or overnight trip.
How to get to the Te Anau Glowworm Caves
Access to the Te Anau Glowworm Caves begins with the RealNZ glowworm tour, which departs from the RealNZ Visitor Centre at 85 Lakefront Drive, Te Anau. This is the check-in point for all tour participants and the departure location for the boat cruise across Lake Te Anau.
Once you’ve checked in, you’ll take a 30–45 minute scenic cruise across the lake to the western shore. From the landing, a short forest walk leads to the Cavern House visitor centre, where your guided cave experience begins.
By campervan or car:
Te Anau is accessible via State Highway 94. The visitor centre is located on the lakefront near the town centre, within walking distance of most shops, cafés, and holiday parks.
Once on the boat, you'll cross the lake to the western shore. From there, it’s a short walk to the Cavern House and the cave entrance, where the guided tour begins.
Best time to visit Te Anau Glowworm Caves
The best time of year to visit the Te Anau Glowworm Caves is during autumn (March–May) or spring (September–November). These shoulder seasons typically offer milder weather and fewer crowds, resulting in a more relaxed and intimate experience.
For the best time of day, consider booking an evening or late afternoon tour. These sessions tend to enhance visibility inside the cave, as your eyes are already adjusted to lower light. The glowworms are most noticeable in complete darkness, and less ambient light outside often improves the viewing conditions.
The caves remain open year-round, with tours operating in most weather conditions unless the lake crossing is unsafe.
Weather at the Te Anau Glowworm Caves
The interior of the Te Anau Glowworm Caves maintains a steady temperature of 8–12°C year-round, so it’s cool regardless of the season. Layers are recommended, particularly for the lake cruise and time spent outside the cave.
In Te Anau, seasonal weather is typical of a temperate alpine region:

Best place to park your campervan at Te Anau Glowworm Caves
