Most of the guests at Duffys of Ballybin self-catering accommodation arrive with cars, which is the easiest way to get around the countryside.
However, there is also quite a good bus service, from bus stops around 2km from the farm. The 103 bus goes from Ratoath to Dublin via Ashbourne. The 105 services the Ratoath/Ashbourne to Blanchardstown route and will also bring you to Tayto Park. The 109 bus goes between Ratoath/Ashbourne and Dublin Airport.
If people want to go out for the evening and to leave the car behind, they can call one of the local taxi companies, such as Ashbourne Cabs (+353-1-8356000); Tara Cabs (+353-1-8352000); or Nuruz on 085-7395131.
If you have the MyTaxi app on your phone, you can summon a taxi without having to give directions to the taxi driver and without needing cash to pay them, since they accept electronic payments.
