Visit the Hampstead Heath, take at least half days time and a well prepared pic-nic bag and maybe a kite to fly at the Parlament Hill. Do not miss the Kenwood House http://en.wikipedia.org/wiki/File:Kenwood_House.jpgu, either where a dozen British films have been made in the Jane Austin - vain. You can also drop by at the Wells tavern on your way (30 Well Walk), Or at the Flask (14 Flask Walk). Lunch at the Freemansons arms, The Food must be forgiven, but there is still something about this place. Especially nice with the kids.
