|Attractions, i.e. things to see, while travelling fall into a few general categories. There are the old and man made (temples, pyramids, ruins*), new and man made (big buildings, bridges), events (whirling dervish show, circuses*, and natural attractions (canyons, waterfalls, caves).
Pamukkale* definitely falls into this last category, but not in any subcategory that I've ever encountered. What looks like snow covered hills is actually eons of deposits of calcium from natural hot springs that flow into naturally terraced pools and down the hillside. When visiting, you take off your shoes and climb up the hillside, wading through the successively hotter pools (making friends along the way). Being that it was a cold day, we headed straight for top pool to wade and dork around. After making it to the top, it is back to category #1, with some spectacular ruins of which I won't post any more pictures*.
Yep, Pamukkale is a great spot. I planned on spending one night. I'm working on my third now. But tomorrow it is back on the road, another amazing set of attractions waiting to be discovered.
