King William III Monument

The monument stands on a hillside overlooking Larne, a straightforward stone obelisk marking where William III landed in 1690 before the Battle of the Boyne. It's not subtle - you'll spot it from miles away, a proper statement of historical significance rather than any architectural flourish.

For history buffs, this is essential viewing if you're tracing the 1690 campaign. You get solid views across the Larne coastline from the monument's location, and the walk up takes twenty minutes or so depending on fitness. Families with older kids won't find it tedious - there's actual historical ground to cover, quite literally.

The site itself is free and accessible year-round, though there's little in the way of interpretation boards or facilities. Bring sturdy shoes - the ground gets boggy after rain. It's worth factoring in as a half-hour stop if you're already exploring County Antrim's coastal heritage sites rather than planning a dedicated trip.

Down to Earth Wild Camping sits about five miles away and gives you a base for exploring this corner of Mid and East Antrim properly. The monument pairs reasonably with a broader coastal walk - Larne itself has the medieval castle ruins and the harbour if you want to make a morning of it. Not life-changing, but authentic and worth seeing if you're in the area.
