There’s no bad day in Auckland – today, yours starts with a city sights tour before you set your GPS for the Waikato River and Waitomo Caves. This place is radiant – quite literally. While cruising cavernous waterways, your route is cast in a magical light by thousands of glowworms. It’s a landscape almost as otherworldly as Rotorua, where mud pops and jettisons from bubbling geysers, and steam rushes skywards from cracks in the Earth. This evening, explore Te Puia’s geothermal valley, and learn about Māori history and culture on this guided experience, which includes a dinner of hangi-inspired cuisine and a cultural performance in a finely carved meeting house, Te Aronui a Rua. It ends on a high at the Pohutu Geyser, where, armed with a hot chocolate you’ll view one of New Zealand’s geothermal wonderlands.
