Larne is a town and port in County Antrim.
The A8 road connects Larne to Belfast. A more scenic alternative is the A2 Antrim Coast Road.
Larne has 2 railway stations, Larne Town and Larne Harbour, both of which are on the same line from Belfast.
There is no reason to linger in Larne so keep going and explore the rest of the country once you get off the boat!
