Had a gloriously sunny day and from the start on the catamaran our young guide captured our interest with his stories of the history of this place, his love for it shone through. A short walk to the cave entrance then bending under the entrance (couple of bumps on the head from looking up too soon!) we walked on metal ramps over the rushing water. . I was amazed how much water and how fast it was going as well as very noisy. The boat took 8 of us, 4 on each side facing outwards, with the guide pulling the boat along on a rope under low ceilings where the lights were magical, certainly looked like fairyland. I wished I had had a hat on to avoid the odd drip onto my head, we had puffer jackets on but it wasn't that cold in February. Once we were out again (more bumps on the head) we had refreshments and listened to our guide from the boat and watched a slide show of the life cycle of the glowworm, all very interesting.
