Our group of nine New Zealanders understood that those who were a bit frail wouldn't be able to go through the caves so two of us stayed in the grounds and enjoyed the wait in beautiful surroundings. The rest of us had a brilliant tour! The young guide was so helpful, friendly and knowledgable. When we turn the lamps off to better see the glow worms the dark is BLACK. I can see how little kids might be afraid so shouldn't join a group and ruin it for others. We will recommend this wonderful tour provided by locals without any flashy props. Well done Kawiti family, this is a grat attraction.
