Any Ideas Where this Place is?

There is something about this photo that makes me want to pack a bag and run barefoot to the nearest airport, jump on a plane and head out into the wilderness in search of this hot bubbling spa. We asked our facebook fans earlier today if they had any ideas where it might be. We've had a lot of suggestions of places all over the world including Turkey, Brazil, Iceland, Belgium, Bath and New Zealand to name but a few. What do you think of the suggestions, only one of them is right by the way, and where do you think this is? Pop your thoughts in the comments section if you will.
