Knaresborough.

Cradled in a horseshoe bend of the River Nidd, this North Yorkshire town is best known for its ruined castle perched high above the water and the petrifying well where visitors once watched everyday objects turn slowly to stone. Knaresborough's steep cobbled streets and riverside walks lead naturally to its cafes for a pause, its handful of restaurants for something heartier, or one of the local hotels if you'd rather stay the night.
