The Cotswolds 
This limestone escarpment, 18 miles north-east of Bristol, overlooking the Severn Vale, is an upland region of stunningly pretty, gilded stone villages and remarkable views. Unfortunately, the soft, mellow stone and the picturesque Agatha Christie charm have resulted in some villages being overrun by coach tourists and commercialism. Renowned villages include Bibury (claimed to be the most beautiful village in England); the chocolate-box town of Bourton-on-the-Water; and the breathtakingly pretty Chipping Camden. The best way to explore the Cotswolds is to walk; the 100-mile Cotswold Way is a gem of a hike, full of history and interesting terrain that make the abundance of quaintness easier to swallow.
