Have been away for the first couple of weeks of the summer holidays but we are now back for the remaining 3. I'm after ideas for some good days out in Kent or Essex suitable for an 11 and 13 year old but where I can also take our puppy. I have Hever Castle on the list. I know he can't go in the castle only the grounds but that is ok. Any other suggestions? He is good off lead but I know many places will require him to be on a lead and that is not a problem.
