Trethem Mill was established in the late 1960’s when a local farmer diversified and sold some of his fields. Our family bought the business in July 1992 and over the years we have transformed the open fields with basic facilities into a multi award winning Park. We have also reduced in size and now have 80 pitches suitable for caravans, motorhomes and tents. We are entirely owned by the family so guests are assured of a genuine welcome from people who care about the Park, as a home as well as a business with an emphasis on attention to detail and customer care
