My house in Groomsport is less than 2 mins walk from sandy Cove Bay. It is in a quiet village with 1 pub and 3 churches. However it is 5 mins drive from the busier Bangor and only 30 mins from Belfast. Here you have the best of all worlds.
Quiet and relaxed beachside location convenient to larger towns and cities. Also good for coastal and country walks and other outdoor activities.
There is a regular bus service to Bangor (less than 10 mins) which links you to the entire bus and train network of Ireland.
