Overview
The Portrush-to-Bushmills Coastal Walk is a linear, point-to-point trail that stretches 13.2 km (8.2 mi) along the world-famous Causeway Coast. Starting at Portrush Harbour, the route threads through sandy bays, rugged limestone cliffs and historic sites before ending in the village of Bushmills. Classified as strenuous, the trail demands confidence: expect steep climbs, uneven natural surfaces, and occasional overgrown sections. The dramatic seascapes and cultural landmarks, however, make it one of the most rewarding coastal hikes in Northern Ireland.
History & Landscape
The coastline this walk follows has served as a gateway for travellers since Norman times. The village of Bushmills, originally known as Portcaman, developed around water-powered mills on the River Bush and later became a key stopping point for visitors heading to the Giant’s Causeway after its wider recognition in the 1690s. Dunluce Castle, perched on a crag just before Portballintrae, dates back to the 13th century and anchors the middle section of the route with medieval drama. The trail forms part of the broader Causeway Coastal Route, a landscape that has inspired generations of writers, artists, and filmmakers.
Key Waypoints & Highlights
Rather than a continuous trail, the walk connects a series of distinct coastal zones. Here is what to expect as you progress:
- 0 km – Portrush Harbour: Your starting point. A historic fishing harbour with parking, cafés, and clear signage.
- 1 km – Ramore Head: Open headland offering panoramic Atlantic views. Ideal for orienting yourself before the terrain gets steeper.
- 2 km – Portandubh Harbour & Countryside Centre: A wildlife-rich nature reserve managed for conservation. Great for quiet observation and bird-watching.
- 3 km – East Strand Beach: A wide, exposed sandy beach. The path follows the shoreline for over 2 km, shifting from hard-packed sand to dune grass.
- 4.5 km – White Rocks Coastal Park: Striking limestone cliffs and a short, steep ascent that brings you back to the A2 road.
- 5 km – Dunluce Castle: The route passes the castle grounds. Ticketed entry to the ruins is optional but highly recommended for the cliff-edge setting.
- 6 km – Portballintrae Village: A small fishing harbour and the junction for the ‘Port Hedge’ track. Good spot for a mid-walk break.
- 8 km – Bushfoot Golf Club car park: A useful shortcut past the River Bushfoot, avoiding a longer detour.
- 9 km – Giant’s Causeway & Bushmills Railway: The UNESCO World Heritage site sits just off the path. The historic hydro-electric tramway runs nearby and offers a scenic shuttle.
- 10 km – Bushmills Station: Marks the end of the historic railway line and provides a direct link into the town centre.
- 13.2 km – Bushmills Village: The walk finishes in the town, home to the Old Bushmills Distillery and several heritage buildings.
Along the way, you can detour to the Lissenduff Earthworks near Portballintrae, explore the traditional Shell Row cottages in Bushmills, or simply pause at any of the numerous cliff viewpoints.
Wildlife & Birdwatching
The stretch between Portrush and Portballintrae passes through coastal habitats that attract seabirds such as guillemots, razorbills and kittiwakes, particularly during spring and early summer. The Portandubh Countryside Centre manages a small reserve where you may also spot otters, seals and a variety of wading birds. Bring binoculars and check tide times; low tide exposes sandbanks that are prime for spotting marine life.
Dog-Friendly Information
Dogs are welcome on most of the trail but should be kept on a lead in exposed cliff sections and around wildlife nesting areas. Fresh water is available at Portrush Harbour and the White Rocks Coastal Park. Coastal winds pick up quickly, and weather can shift without warning, so bring a light jacket and keep your dog close to the marked path.
Best Time to Visit
- Spring (April-May): Wildflowers emerge along the dunes and bird activity peaks. Days are long enough for a comfortable pace.
- Summer (June-August): Maximum daylight makes the full 13 km manageable, but the Giant’s Causeway area draws large crowds. Start early to avoid congestion.
- Autumn (September-October): Temperatures drop and visitor numbers thin. Sea spray against the cliffs creates striking photographic conditions.
- Winter (November-March): The trail remains open but brings stronger winds, rain-slick rocks, and shorter daylight hours. Sturdy waterproof boots and a head-lamp are strongly advised.

Getting there
- By car: Follow the A2 Causeway Coastal Route to Portrush Harbour. Turn left off Dunluce Road onto Causeway Street, then Kerr Street to the harbour car park. Free parking is available at Ramore Head, Portballintrae Harbour, and on-street in Bushmills. Allow 2 hours from Belfast and 2½ hours from Dublin.
- Public transport: Translink routes 172 and 402 run from Dunluce Avenue in Portrush to Bushmills (≈20 min). Check schedules via the Translink journey planner.
- Train: The Enterprise service connects Dublin Connolly to Belfast Lanyon Place. From Belfast, a local train reaches Portrush, where you can transfer to a bus for the walk’s start.
Facilities & Accessibility
- Parking: Free at Ramore Head, Portballintrae Harbour, and on-street in Bushmills.
- Refreshments: Wheelchair-accessible cafés and shops in Portrush, plus a disabled parking space near the harbour.
- Toilets: Available at the Portrush Harbour car park and the White Rocks Coastal Park visitor area.
- Mobility access: The initial harbour promenade and paved stretch along Dunluce Road suit users with limited mobility. The majority of the route features steep sections, exposed rock steps, and occasional overgrown stiles, making it unsuitable for wheelchairs or pushchairs.
Safety notes Surface conditions change frequently. Expect grass, loose sand, exposed rock, and slippery patches after rain. Large roots and uneven steps are common, so sturdy footwear with good grip is essential. The route is not sign-posted for the reverse direction, so carry a physical map or offline GPS. Walk in daylight and check local weather forecasts before setting out.
Nearby Walks & Extensions
If you have extra time, these routes complement the coastal experience:
- Antrim Coast and Glens: A longer circular route linking Portrush with the dramatic inland glens of north-Antrim.
- Ballycastle Heritage Trail: A short drive east brings you to Ballycastle, where a heritage trail explores maritime history and connects to the Dark Hedges.
- Carrick-a-Rède Rope Bridge: Just a few kilometres north of Bushmills, this suspension bridge offers direct Atlantic views and is a popular stop for photographers.
Plan your return transport before you start. The Translink bus from Bushmills back to Portrush runs regularly, but schedules tighten in the evenings, so check the timetable ahead of time to avoid a long wait at the terminus.
