That dryout may explain why the only video for this place seems to be 2 to 8 years old. The interior of Turkey is not somewhere I would go lightly, as I already used up my 9 lives in fringes of Africa, Asia, and S. America. Transport tends to be by long busrides with language problems. Travelers gush about the friendly reception, but there are safety reasons for this (dated) chart showing dropoff of European tourists (leaving mostly Russians at the time):
I yearn to visit various coastal spots like Ephesus, and had mainly thought about Pamukkale pools below for the interior. But Sankaya baths are a long way from there. I suppose you could combine the Baths with visit of the Cappadocia region which is an (inconvenient - see bottom) tourist magnet for reasons I don't really get.
