Bath

Our first view of Bath was from the train on the way to Cardiff - we both looked out the window and said "oooooh look at that - what's that place?". We had still been deciding where to go for a day trip from London, but that decided it =)
It was just beautiful - the abbey and Roman baths are so impressive, and then there's the gorgeous countryside all around.
Bath is definitely on my must visit again list - we'd love to spend a couple of days there at least.
