Come along and enjoy an exciting weekend of sport in our stunning North Yorkshire parkland with Allerton Castle in the background. Take a walk in the countryside by the lakes with their swans and other wildlife. Bring a picnic, or have a relaxed snack at one of our catering facilities watching the show jumping, or the thrills and spills at the water jump. Look round our tradestands and enjoy the atmosphere of the competition. Our scenic venue is easily accessed from the A168, just south of Boroughbridge.
