Hi Steve. There are two Caravan Club Sites, not sure if they take non members, one called Beechwood Grange an excellent site open until the 7 November on the outer ring road. We just spent time there during the York Motorhome Show. Very easy to travel into York. The other is Rowntree Park open all the year round in the centre of York and near to the Race Course but you have to check it is not flooded if there has been lots of rain! If you would like more details of these just say and I can post them for you. Hope you enjoy your stay in York it is a lovely city.
