Heading to the Scottish borders, we needed to find an overnight stop on the A1 loosely south of Doncaster. Milestones fitted the bill perfectly and we were not disappointed. We booked an overnight stop with electric and no awning and were given an easily accessible pitch near to the reception building and the loos. We had time for a wander around the site - it is a bit like a floral park with neatly maintained borders and grass areas, plus fishing lakes. Would happily stay here again, but next time I'll make it a couple of nights and explore what the area has to offer.
Access is off an old section of the Great North Road that has been bypassed by the new A1 that runs parallel. There is an access to the south and also to the north. I'd suggest using the north access (after the BP garage when heading north) and coming back on yourself a little as the road to the south appears to be used as a layby for lorries and looks to have a rough surface.
The downside of being close to the A1 is that it is a busy road 24 hours a day, so there is always some background noise. But as it is constant, you soon get used to it and block it out
