Our first time here, I understand why you need to book so far in advance! Its in a great location, easy walking distance to city centre, local shops, local pubs and of course the river. We stayed for 2 nights from 3rd July, the site was almost full, we arrived just after 2pm, but managed to get a pitch near the middle of the site, so we were not bothered by the park, which is next door. The facilities here are great, spotless, and the site very clean. We have 2 dogs and although there is no dog walk on site, you can take your dogs for a walk outside the site and into Rowntree Park (on a lead) - the park itself is really pretty and peacful. We took our dogs for a long walk along the river, past the Millenium bridge and they can run free, we walked up to Bishopthorpe Palace and then crossed over the river and walked back the other side. Most of the pubs seem to be dog friendly, close to the site and into the city, and not only in the beer gardens but also welcome you inside. This is a great site for visiting the city and for the races. We are looking forward to returning in September.
