Not exactly your typical eco retreat, this bohemian 10-room country hotel in the market town of Swaffham is a Grade II-listed Queen Anne villa with canopied four-poster beds, open fires, stripped wooden floorboards and free-standing baths. Its award-winning restaurant serves mostly seasonal, organic food, and almost every conceivable aspect of the running of the hotel has been designed to reduce its draw on energy and minimise waste and packaging. There's a 10 percent discount if you arrive by public transport: take the train to King's Lynn then X-1 bus to Swaffham.
