You’ll have to go underground in this small North Island village to understand its blockbuster appeal. Though Waitomo’s surrounding landscape of rolling, green hills has postcard allure, a maze of flooded caverns called the Waitomo Caves is the starring attraction. Things to do in Waitomo include boat, raft, and spelunking tours of the underground network, which comprises the Waitomo Glowworm Caves, Ruakuri Cave, and Aranui Cave. Tours follow underground rivers illuminated by thousands of glow worms—native, bioluminescent insects that emit a soft light, giving the stone cavern walls an otherworldly beauty.
