"Floating through the Waitomo glow worm cave felt like staring at the stars—except the lights are bioluminescent gnats—and the experience (walks, boat tours, or abseiling options) is touristy but still amazing. I found the three-hour trip long enough, though the five-hour abseil version is for adventurers; prices start around 79 NZD for a boat tour, ~113 NZD to just walk around the caves, and ~195 NZD for extended tours with abseiling, and this remains one of my most lasting memories from New Zealand." - Matthew Kepnes
