I've done 6 of those.
2, 8, 12, 18, 27 and 37.
I personally don't like these sorts of lists- it's like top 10 'sexy' women--it is somebodies personal taste dictating to others what they think is good. I think it a touch obnoxious! Not to mention the carbon footprint you'd leave behind
There's a few places in the UK they've missed out on- the Lake Districts, Snowdonia, Cornish Beaches and Scottish highlands are all absolutely stunning places to visit before you shuffle off the coil for good.
