On a day-trip from London post in another forum someone mentioned evening viewing of the baths with torch light.
Since the info belongs hee, this is what I found. Any local feedback to what it's like (worthwhile?!) would be welcome!!!!
I was intrigued by the post about the Roman Baths and torchlit evening viewing.
... I found that the baths will be open evenings in May and then all thru July-August, torchlit and all!
First is May 12, see
And then again in July/August
this link has a photo too.
