The respective tourist board websites will provide much info...

England - http://www.enjoyengland.com/
Scotland - http://www.visitscotland.com/
Wales - http://www.visitwales.co.uk/
Northern Ireland - http://www.discovernorthernireland.com/
Ireland - http://www.discoverireland.com/gb/
Britain as a whole - http://www.visitbritain.com/

Wikipedia has lots of info...
E - http://en.wikipedia.org/wiki/England
S - http://en.wikipedia.org/wiki/Scotland
W - http://en.wikipedia.org/wiki/Wales

And the BBC site also has lots of info, you'll find much about the lifestyle here...

Just to avoid confusion: Ireland isn't part of the UK but Northern Ireland is.
