The World Heritage–listed saucer-shaped travertines (or terraces, as they are also called) of Pamukkale wind sideways down the powder-white mountain above the village, providing a stunning contrast to the clear blue sky and green plains below. To protect the unique calcite surface that overruns with warm, mineral-rich waters, guards oblige you to go barefoot (or in socks or shower shoes), so if you're planning to walk down to the village via the travertines, be prepared to carry your shoes with you.
Although the ridges look rough, in reality the constant water flow keeps the ground mostly smooth, even gooey in places, and the risk of slipping is greater than that of cutting your feet. To walk straight down without stopping takes about 30 minutes. The constant downward motion can be hard on the knees.
Although the terrace pools are not particularly deep, you can get fully submerged in the thermal water. There is a gushing channel of warm water at the top of the path down through the travertines, where representatives of many nations sit and give their legs a good soak. If you do not have a bathing suit or shorts, or otherwise do not wish to get too wet, there are plenty of dry sections leading down. Also note that going at midday means crowds and sharp sunlight reflecting off the dazzling white surface; later in the afternoon is better.
