This Spellbound Tour involves rafting on a regular raft (not in an inner tube) through the breathtaking Mangawhitikau cave system. It is less touristy than the more popular tours of the main Waitomo Glowworm Cave and you can take photos in this cave. Spellbound even operate a longer version of the tour specifically for photographers taking time exposure photos with a tripod.
It is one of the cheaper ways to see the glowworms, but it’s not as much fun as more expensive adventure-focused trips.
