Planning
A Fiordland day around the caves
How the glowworm caves fit around Te Anau's other trips: a Doubtful Sound day, a jet boat run on the Waiau River, the tracks and the bird sanctuary.
Book the glowworm caves ↗Quick answer
The caves take about 135 minutes, so they pair with a short activity on the same day but not with an all-day fiord cruise. Te Anau is the gateway to Fiordland National Park, and the nearby options are a Doubtful Sound day from Manapouri, a jet boat run on the Waiau River and the park's walking tracks.
Te Anau as a base
Wikipedia says Te Anau is a small town on the eastern shore of Lake Te Anau, with an estimated population of 2,920 in June 2025, and calls it the gateway to a wilderness area famed for tramping and spectacular scenery. It is the closest town to Fiordland National Park, which is the largest of New Zealand's 13 national parks. The caves lie across the lake, and the lakefront check-in is where the trip begins.
The park around it
Wikipedia gives Fiordland National Park's area as 12,607 square kilometres, in the south-west corner of the South Island. It has 15 fiords and, with other parks, forms the Te Wāhipounamu World Heritage Site, designated in 1990. Prevailing westerly winds bring rainfall that exceeds seven metres in many parts of the park, so a day plan that includes a boat or a walk is best made with weather in mind.
A Doubtful Sound day
Wikipedia says Doubtful Sound tours depart from Manapouri, with a boat transfer across Lake Manapouri and a bus transfer over Wilmot Pass. The booking for the Doubtful Sound coach and cruise from Te Anau describes the same shape: a coach to Manapouri, a lake cruise, a coach over Wilmot Pass and a three-hour cruise on the fiord, in about eight and a half hours. It suggests bringing your own lunch. Dolphins, seals and penguins are things to look out for, not promises.
A jet boat run
The jet boat and nature walk from Te Anau is the shortest of the nearby options at about two hours. The booking describes a 75-minute jet boat ride down the Waiau River to Lake Manapouri and a guided nature walk of about 15 minutes. It says the river appears in the Lord of the Rings films as the Anduin, that you should expect some water spray, and that the trip is not suitable for children under four. It is a different kind of outing from the quiet of the caves.
The walking tracks
Wikipedia says the Milford Track starts at the northern tip of Lake Te Anau, and the Kepler Track starts and ends at the southern tip, at the Waiau River. It calls the Kepler a four-day loop that starts from the town, and says trampers often use Te Anau as a base for both tracks. Wikipedia also says Manapouri lies about 21 kilometres south of Te Anau, and that a 28.5-kilometre cycle trail follows the Waiau River between the two lakes.
The bird sanctuary
Wikipedia describes a bird sanctuary on the southern shore of the lake, Punanga Manu o Te Anau, where visitors can see takahē, kākā and other native birds. A takahē statue stands in town. The takahē was rediscovered in the Murchison Mountains in 1948, the same range as the caves, and the sanctuary is a way to see the bird without going near the protected area itself.
How to combine them
The caves last about 135 minutes, so they fit with a short activity such as the jet boat run, or with a walk or a visit to the sanctuary. They do not fit the same day as an eight-and-a-half-hour fiord trip. If you have two days, put the long trip on one and the caves on the other, and keep a spare day for weather. Both bookings offer free cancellation on GetYourGuide, which makes a late change less costly.
Who this isn't for
Anyone hoping this site will name the single best Fiordland day: it cannot, because the trips are so different. Anyone who needs step-free access, because the caves and the jet boat both involve steps or movement. Anyone expecting to fit every option in one day, which no timetable allows. Choose the one trip that matches your interests and the weather, and treat the rest as the next day's plan.
