A 6-Day North Island Road Trip Through New Zealand’s Volcanic Heart
If you want one North Island road trip that covers the volcanic side of New Zealand, the Thermal Explorer Highway is hard to beat. It starts in Auckland, cuts through the middle of the island and finishes in Hawke’s Bay. Along the way you get glowworm caves, a hobbit village, steaming geothermal parks, a mountain national park and a proper wine region.
Tourism New Zealand recommends six days for it. That’s enough to enjoy each stop without spending the whole trip behind the wheel. Watch for the brown themed-highway signs as you drive. Most of this route is signposted, so you only need a map when you detour.
The Thermal Explorer Highway at a glance
- Route: Auckland to Hawke’s Bay (Napier)
- Recommended time: 6 days
- Best for: self-drive travellers, Lord of the Rings fans, hot pool lovers, wine drinkers
- Good to know: combined with the Pacific Coast Highway, it forms the Great New Zealand Touring Route
Day 1: Auckland to Waitomo
Leave Auckland early and head south on State Highway 1. Hamilton is about an hour and a half away, and Hamilton Gardens is a good place to stretch your legs and get some coffee. From there it’s about an hour to Waitomo.
The Waitomo glowworm caves are the main event of the afternoon. Drift through the dark by boat under thousands of tiny blue-green lights, or go further with a cave walk. If you want more adventure, Waitomo is also known for its underground river rafting. Book ahead in summer, because the popular tours sell out.
You can browse more options on our Waikato and Waitomo page.
Day 2: Waitomo to Rotorua via
It’s a bit over an hour to Matamata, home of the Hobbiton movie set from The Hobbit trilogy. Tours last about two hours and run on timed slots, so book before you go. Even if you’ve never watched the films, the gardens are worth the stop. If you have, our Lord of the Rings tours cover more filming locations.
Rotorua is another hour down the road. You’ll smell it before you see it, because the sulphur gives the city its eggy signature. After dinner, find a hot pool and let the driving fall off your shoulders. Our guide to the best hot springs in New Zealand can help you choose.
Day 3: A full day in Rotorua
This is the one day you don’t drive far, and you’ll want it. Rotorua geothermal attractions and Māori culture sit side by side here.
Spend the morning at a geothermal park such as Te Puia, where geysers and bubbling mud pools share the site with carving and weaving. Then visit a living Māori village or take in a cultural performance. For a free alternative, Kuirau Park in the middle of town has steaming vents and hot foot baths.
If you need some fun after all that culture, Rotorua is also where you can roll down a hillside inside a giant inflatable ball. Browse more on our Rotorua page, or see our pick of Māori cultural experiences.
Day 4: Rotorua to Taupō
Head south on State Highway 5 and make Wai-O-Tapu your first stop. It’s about 30 minutes out of Rotorua, and the colourful pools are the reason many people do this route. Check the geyser eruption time when you book, and arrive with time to spare.
If you prefer a quieter thermal valley, Orakei Korako is a short detour off the highway. Then continue to Taupō, stopping at Huka Falls and the Aratiatia Rapids on the way in.
Finish the day on the lakefront. Lake Taupō is the country’s largest lake, and the sunsets over the water are worth waiting for. More things to do are on our Taupō page, and our volcanic and geothermal category has extra ideas.
Day 5: Tongariro National Park
Tongariro National Park is about an hour and a half from Taupō. It’s a dual World Heritage area with three volcanoes, snow-capped for much of the year, and it’s one of the big reasons this route exists. Mount Ngauruhoe also played Mount Doom in the films.
What you do depends on your fitness and the season:
- Serious hikers: the Tongariro Alpine Crossing is a long one-way day walk of roughly seven to eight hours. It needs a shuttle booking, decent fitness and good weather, because conditions up high change fast.
- Easier option: short walks around Whakapapa Village, including the Taranaki Falls loop, give you the scenery without the commitment.
- Winter: the ski fields on Mount Ruapehu are open, so this day can turn into a snow day instead.
Head back to Taupō for the night. See our Ruapehu region page and our list of walking and hiking options for more detail.
Day 6: Taupō to Hawke’s Bay
The drive to Napier on State Highway 5 takes around two hours, closer to three with stops. It’s winding in places, so check the NZTA Journey Planner before you leave, since weather and roadworks can cause delays.
You finish in Hawke’s Bay wine country, one of New Zealand’s best-known wine regions. Spend the afternoon tasting at a winery (the Gimblett Gravels is famous for its reds), then head into Napier for its art deco architecture. Finish with dinner on the waterfront.
If this is your final stop, you will arrive with only half a day in the region. See our Hawke’s Bay page and our wine tours to plan it.
Planning tips
When to go. The Thermal Explorer Highway works year-round. Summer suits hiking at Tongariro, while winter opens the ski fields. Our guide to the best time to visit New Zealand breaks it down by month.
Driving. New Zealand drivers keep left, and rural roads are slower than the map suggests. Read our driving in New Zealand guide and our car rental page before you book. One-way rentals from Auckland to Napier can carry a drop-off fee, so check that first.
Getting home. The route ends in Hawke’s Bay, not Auckland. You can fly out of Napier or drive back, but either way you’ll want to plan it early.
Add a day if you can. Six days works, but a seventh in Hawke’s Bay lets you taste wine without rushing.

FAQ
How many days do you need for the Thermal Explorer Highway?
Six days is the recommended length from Auckland to Hawke’s Bay. Go shorter and you’ll skip stops, and go longer if you want more time in Rotorua, Taupō or the wine region.
Where does the Thermal Explorer Highway start and finish?
It starts in Auckland and finishes in Hawke’s Bay, passing through Hamilton, Waitomo, Rotorua, Taupō and Tongariro National Park.
Can I drive it in the other direction?
Yes. Many travellers start in Hawke’s Bay and finish in Auckland, which also makes flights home easier.
When is the best time to drive the Thermal Explorer Highway?
You can drive it all year. Summer is best for walking at Tongariro and long days on the road, while winter brings snow and open ski fields on Mount Ruapehu. Spring and autumn are quieter, with fewer crowds at the big attractions.
Do I need to book activities in advance?
For the popular ones, yes. Hobbiton tours run on timed slots, Waitomo cave tours can sell out in summer, and the Tongariro Alpine Crossing needs a shuttle booking. Hot pools and geothermal parks are easier to fit in on the day, though booking ahead is still safer in peak season.
Can I do it without hiring a car?
Yes, though it takes more planning. Coach tours are an option if you’d rather not drive, so have a look at our independent coach tours to see what fits. A rental car still gives you the most freedom, especially for detours like Orakei Korako.
