Denizli Provence in southwestern Turkey!
Okay, well not exactly swimming in the clouds, but close to it! This is a twist on your typical beach vacation; the views from the ‘cotton castle’ are of better quality than any pool or beach; you can receive that sun kissed tan while staying toasty in the naturally warmed spa while also experiencing magnificent views of the valley below.
You would also be relaxing/bathing in something historical, these travertine hot springs have been used as a spa since second century BC!
