As a major port for ferries from Scotland, Larne (Lutharna) is one of Northern Ireland's main points of arrival. However, with its concrete overpasses and the huge chimneys of Ballylumford power station opposite the harbour, poor old Larne is a little lacking in the charm department. After a visit to the excellent tourist information centre, there's no real reason to linger.
Larne Harbour train station is in the ferry terminal. It's a short bus ride or a 15-minute walk from here to the town centre – turn right on Fleet St and right again on Curran Rd, then left on Circular Rd. At the big roundabout, Larne Town train station is to your left, the tourist office is to the right, and the bus station is ahead (beneath the road bridge).
