I found the visit to the underground caves breathtaking. It was truly scary at first, especially knowing the place hasn't been much explored before. But we had a knowledgeable guide and safety equipment, so the excitement soon replaced the fear. The caves were bigger than I expected, and so silent that we could hear our own breaths and heartbeats. We needed flashlights to be able to look around, and the guide warned us there might be a few bats in at least one of the caverns. We also got to see some stalactites. As we kept on going, we reached a larger cave that had a sort of skylight - an opening on its ceiling that allowed light to flow in. We were able to turn our flashlights off at this point we simply enjoy the natural spectacle. I had a lot of fun. This was an unforgettable experience for me.
