We've booked a night in York on the way up. We don't want to stay overnight on way home but would like somewhere to stop for an hour or 2 and have a picnic lunch. We don't want a service station as we consider the journey part of the holiday! I see Doncaster is the exact halfway point but not sure if anything nearby. A couple of possibilities are Aysgarth Falls in the Yorkshire Dales or Eyam in Derbyshire, both of which look interesting. However, both add at least an hour to journey. We're NT members so if we can utilise that even better! (I see Eyam is NT).
Thanks.
