Went caving and tubing at Waitomo glowworm caves. We had to fit through small gaps in the rocks that we thought was not possible. It was but only if we were facing face down in the mud and eel filled waters using our elbows and knees to push us through. It was so much fun though. When we finally reached the parts of the caves with the glowworms we switched of our helmet lights, sat on an inner tube and floated through the water staring up at the thousands of glowworms that lit up the cave.
