The only downside was that all of them were overly illuminated with garish coloured lights; that seems to be the trend in Asia. Phong Nha Cave in central Vietnam suffered from the same decorative affliction when I saw it last October.
I saw my first cave when I was 10: Yallingup Cave in southern Western Australia. My parents bought me a souvenir book, which I remember paging through for months (years?) afterwards. It's amazing how much I still retain. I could declaim "Helictites!" when I spotted them these couple of days, and tsk-tsk at visitors who touched the limestone formations (hello, way to contaminate the calcium carbonate). I mean, seriously, there was a guy at Daegeumgul today who touched every other formation hanging over our path as we finished the tour, with the kind of rapping one usually associates with checking for secret chambers. What, did he think the limestone formations were hollow and fake?
Besides the caves, there've been countless beaches, and the usual rounds of restaurant and hotel visits. This is the last I'll see of Korea's east coast on this trip. Tomorrow I'm headed inland to more national parks.
