The two and a half hour Belsize Walk links Primrose Hill with Parliament Hill, passing the many architectural highlights of the Belsize conservation area.
It is a lovely stroll on a summers day, although you can't help but feel eyes following you if you lower yourself to such undignified activities as taking photos or consulting a map.
Belsize Walk (via Russell Davies):
To start with it was pleasant, but kind of boring, I wasn't suprised to learn that a lot of Belsize was developed as a rival to Kensington - it's got the same big, blandly impressive feel. If slightly untidier - full of academics and lawyers rather than Eurotrash and models.
So I was quite pleased to see a bit of tagging on a wall, made the place feel a bit more lived in.
