The Causeway Coastal Route runs between Belfast and Derry~Londonderry, threading together some of Northern Ireland’s best-known landscapes, historic sites, and coastal towns.
Planning Your Trip
May to September generally offers the most reliable weather and the widest range of open attractions. Self-driving gives the most flexibility, though seasonal public transport (Ulsterbus 252, the Goldline Coach Service 221) and guided tours are both viable alternatives. Accommodation ranges from B&Bs and hostels to converted historic properties like Ballygally Castle - book ahead in peak season.
Top Attractions
Carrickfergus Castle, a Norman stronghold that has stood on Belfast Lough for over 800 years (built around 1177), makes a natural starting point. Inland, Glenariff Forest Park offers its popular Waterfall Walk past three waterfalls. The Giant’s Causeway, a UNESCO World Heritage Site, showcases hexagonal basalt columns formed by cooling lava around 50-60 million years ago - or, by local legend, built by a giant as a crossing to Scotland. Dunluce Castle, a dramatic clifftop ruin further along the coast, rounds out the classic stops.
Outdoor Activities
The route supports hiking (from Fair Head’s cliffs to the gentler slopes of Binevenagh), cycling, and watersports along the coast, alongside wildlife including red squirrels, seabird colonies, and seals.
Food and Drink
Expect hearty local fare - the Ulster Fry, Irish stew - alongside food festivals like the Salmon and Whiskey Festival in Bushmills, farmers’ markets, and a strong pub and restaurant scene throughout.
Practicalities
Remember to drive on the left, and pack for changeable Northern Irish weather regardless of season.
