The Port of Mostyn is privately owned and operated. It is a Statutory Harbour Authority and is also the Pilotage Authority for the Dee Estuary. Located on the south bank of the Dee Estuary in North Wales, the port is served by a good road infrastructure linking up with the motorway network joining the M6 and the M62 corridor. In addition to the road network, the port has its own railway siding linking it directly to the main national rail network.
