This article is about the Class III road numbered C365 maintained by DfI Roads. For other roads numbered C365, see C365.
The C365 was formerly part of the B27 which used to extend from its present day ending point in Kilkeel all the way out to Greencastle on the shores of Carlingford Lough. The road starts on the A2 in Kilkeel and follows Greencastle Road south westwards out of the town. The road passes the C316 as it makes its way towards Cranfield. Soon the road TOTSOs west, then north and then west again. North of Cranfield Bay the road crosses the C317 at a crossroads and continues west. The road passes the ferry terminal for the ferry service across the lough to Greenore, County Louth. Just beyond the terminal the road itself ends as it curves round into Greencastle.
