To ask where you'd recommend for a thermal spa (ie natural hot springs) that isn't any of the following

[Fragmentedbrain]

1. In Iceland
2. In Hungary
3. With rules compelling nakedness (ideally with noone being naked but I'm a realist so just somewhere I can keep my swimming costume on and eyes lowered is great)

Ischia, Italy.

This is my mastermind subject! I have pasted some of the pages I have saved.l ready for when I 'need to mineral'. I have a look for cheap flights on skyscanner and see if there is a spa town nearby! Make sure you pack spa shoes.

You can then get the narrow gauge railway to Bansko and visit 2 mineral villages a short taxi ride away

There are also lots outside Europe but it is a bit more of a mission (and expense). Hope you find somewhere.

Can recommend Pammukale. it wasn't nude yonks ago, but that may have changed now.
