About Cambridge

King's College Chapel and the Bridge of Sighs at St John's are the set pieces, but the pleasure is in the lanes between them and the lawns that run down to the river. Punting from Mill Lane or the Quayside shows the Backs from the water, and the Fitzwilliam Museum fills a grey afternoon. May through September brings the warmest, longest days; July and August are busiest, so early mornings are worth the effort.
