Portrush to Bushmills – Causeway Coast walk

Overview

The Portrush-to-Bushmills walk covers 10.6 km (6.6 miles) of the Causeway Coast one way, from Portrush Harbour through sandy bays and clifftop paths to the edge of Bushmills. Official sources rate it moderate, not a hard slog – but it’s a real coastal walk, with steep steps, exposed rock and a few stiles once you leave the paved opening stretch, so wear boots with grip. If you do one section, make it the middle: White Rocks to Dunluce Castle, where the cliffs and the castle ruin do the heavy lifting. Allow three to four hours with stops.

One thing to know up front: this walk does not reach the Giant’s Causeway. The Causeway sits about two miles beyond Bushmills and is reached separately (see below). The walk ends at Bushmills Station, roughly half a kilometre short of the village centre.

History and landscape

Bushmills, originally Portcaman, grew up around water-powered mills on the River Bush and later became a stop for travellers heading to the Giant’s Causeway. The set-piece of the route is Dunluce Castle, a ruin on a sheer crag just before Portballintrae, with parts dating to the 13th century and much of what stands built around 1500. The whole walk forms part of the Causeway Coastal Route.

Key waypoints

Rather than one continuous path, the walk links a series of coastal stretches. Here’s the run of it:

• 0 km – Portrush Harbour: the start. A working fishing harbour with parking, cafés and clear signage.
• 1 km – Ramore Head: open headland with Atlantic views, and the last easy walking before the ground gets rougher.
• 1.5 km – Portandubh Harbour & Countryside Centre: a managed nature reserve, good for quiet birdwatching. Portrush’s Coastal Zone here has a small marine exhibition and discovery pools.
• 2–4 km – Curran Strand / East Strand Beach: a wide, exposed beach; the path follows the shoreline for about 2 km, shifting from packed sand to dune grass.
• 5 km – White Rocks: striking limestone cliffs and a short, steep climb back up to the A2.
• 6.5 km – Dunluce Castle: the route passes the castle grounds. Entry to the ruin is ticketed and optional, but the cliff-edge setting is the best thing on the walk.
• 8 km – Portballintrae: a small fishing harbour, and a sensible spot for a mid-walk break.
• 9 km – Bushfoot and the old railway path: the route joins the line of the old tramway past Bushfoot, avoiding a longer road detour.
• 10.6 km – Bushmills Station (Ballaghmore Road): the walk finishes here, about half a kilometre from the village centre and the Old Bushmills Distillery.

Extending to the Giant’s Causeway

From Bushmills Station, the Giant’s Causeway & Bushmills Railway runs the two miles out to the Causeway itself. It’s a heritage diesel service on the line of the world’s first hydro-electric tramway, opened in 1883, and typically runs Fridays to Sundays, May to October, with a handful of trains a day between late morning and mid-afternoon. Check the timetable before you count on it – the schedule is seasonal and limited.

Wildlife

The stretch between Portrush and Portballintrae runs through coastal habitats that draw seabirds – guillemots, razorbills and kittiwakes – especially in spring and early summer. Around the Portandubh reserve you may also spot otters, seals and wading birds. Bring binoculars and check tide times; low tide uncovers sandbanks that are prime for spotting marine life.

Dogs

Dogs are welcome on most of the trail but should be kept on a lead in exposed cliff sections and around nesting areas. Fresh water is available at Portrush Harbour. Coastal winds pick up fast and weather shifts without warning, so bring a jacket and keep your dog close to the marked path.

Best time to visit

• Spring (April–May): wildflowers along the dunes and peak bird activity, with long enough days for a comfortable pace.
• Summer (June–August): the most daylight for the full 10.6 km, though Bushmills and the Causeway get busy if you’re extending the day – start early.
• Autumn (September–October): fewer people, and sea spray against the cliffs makes for good photographs.
• Winter (November–March): the route stays open but brings stronger winds, rain-slick rock and short days. Waterproof boots and a head-torch are wise.

Getting there

• By car: Follow the A2 Causeway Coastal Route to Portrush Harbour. Free parking is available at Ramore Head, Portballintrae Harbour and on-street in Bushmills, with disabled bays at each. Allow about 2 hours from Belfast and 2½ from Dublin.
• Public transport: Translink routes 172 and the seasonal 402 (Causeway Rambler) run between Portrush (Dunluce Avenue) and Bushmills; the Goldline 221 also serves the route. Check schedules via the Translink journey planner.
• Train: Portrush is on the rail network via Coleraine; from Belfast, take the train to Coleraine and change for Portrush, then it’s a short walk to the harbour start.

Facilities & accessibility

• Parking: Free at Ramore Head, Portballintrae Harbour and on-street in Bushmills.
• Refreshments: Wheelchair-accessible cafés and shops in Portrush.
• Toilets: Available at the Portrush Harbour car park.
• Mobility access: The opening promenade and paved stretch along Dunluce Road suit users with limited mobility. The rest of the route has steep sections, exposed rock steps and stiles, so it’s unsuitable for wheelchairs or pushchairs.

Safety notes Surfaces change constantly – grass, loose sand, exposed rock and slick patches after rain. Sturdy footwear with good grip is essential. The route isn’t signposted in the reverse direction, so carry a map or offline GPS, walk in daylight, and check the forecast before setting out.

Nearby walks and extensions

• Antrim Coast and Glens: a longer route linking Portrush with the inland glens of north Antrim.
• Ballycastle Heritage Trail: a short drive east, exploring maritime history and connecting toward the Dark Hedges.
• Carrick-a-Rede Rope Bridge: further along the coast, a popular stop for the crossing and the Atlantic views.

Sort your return transport before you start. Buses from Bushmills back to Portrush run regularly, but the timetable tightens in the evenings – check it ahead so you’re not left waiting at the terminus.
