The tour guide was excellent. The trip inside the caves was very hard as we had to walk in crab fashion bending close to the ground and sometimes the only way to navigate the narrow space in the caves was to roll across. Nevertheless it was awe-inspiring as we saw the various formations of rocks and the imprints on rock left by the molten lava as it flowed through. On reflection, I shudder to think what might have happened if an earthquake had occurred whilst we were in the caves! My only advise is, please make it clear on your website that this trip should be taken only by those who are very physically fit and able to contort their bodies to go through the caves.
The guide was terrific, however, the actual cave tour was disappointing. It was more like a tunnel than a cave, and it was mostly just crawling through the tunnel with not much chance for photo taking.
The guide was friendly and jovial, however, the trip was slightly marred by a 1.5 hour delay from 6-7 of the participants being lost in the cave. Certainly not a trip one will forget, but perhaps for the wrong reasons. The ratio of participants to guides was far too high, and I would choose to go on a trip with a maximum of 8-10 participants going forward.
