Awww, I've been to many caves, and I love it! It's like being in another world, isolated from the worries outside. There's an awesome cave in Japan with magnificent views. There's some artificial light inside and measures to stop people from damaging the ages-old rocks. And right outside (there are two entrances, one below in the city, and one above in the mountain), there was a long mountain road right outside the building where the elevator was. The view was also amazing. I was reminded of it because of your last picture. A beautiful cave and right afterward a beautiful open landscape with pines and foreign smells.
