Pamukkale

And so the the white terraces of Pamukkale. Stunningly beautiful, like nothing you've seen. Shoes must be removed, and so we walk barefoot across white calcite formations with water running down. Every so often a pool of water. David was here 25 years ago when this was a sealed road and he stayed in a hotel at the top. Since gaining World Heritage status, all the hotels have been removed and the road integrated back into the natural pool system. As best I understand it, springs at the top of the hill lose their carbon dioxide as they flow downhill, leaving deposits of white calcium carbonate, which builds up in steps. In the late afternoon sun, the deposits and pools are spectacular! 

And to top it off, so to speak, there is a substantial ruined Roman city of Hierapolis. We spend a couple of hours looking around - especially at the large restored theatre (impressive) and an isolated Martyrion of St Philip with 8 arches and crosses high up above the city. We've just about got it all to ourselves. Wonderful day.
