Waitomo Glowworm Caves were awesome but unfortunately you were not allowed to take photos. There are some on the official web site to give you an idea.
It was an amazing site to see the caves lit up like the stars in the night sky and knowing it was all down to little worms!
After the Glowworm caves we also visited Aranui cave, where we could take photos. The Aranui caves are home to millions of limestone stalactites.
