About Larne

Learn more about the host city, Larne.

Larne is a port in County Antrim, Northern Ireland. The main reason to come is for the ferry link from Scotland, but the town is close to the Antrim Glens. However there's a surprising collection of sights right on the doorstep of town. Just south is Islandmagee, where The Gobbins is Ulster's answer to the Italian via ferrata. All around are glens where streams roar out of the Antrim hills over waterfalls and cascades. The best known are to the north, the nine Antrim Glens; those closest are described on this page. Take the time to explore them and don't just hurry down the well-worn track to Giant's Causeway.
