A commuter village with a hidden past
Seahill is a residential village on the County Down shore of Belfast Lough, joined now to Holywood and the Greater Belfast sprawl but still counted as its own place, with a population of just over 1,000 at the 2011 census. It’s not a destination in its own right. You come for the two miles or so of the North Down Coastal Path that pass through it, and for what sits, easily missed, right beside the trail.
That thing is a war ruin. During the Second World War a prisoner-of-war camp and American army base stood here, and the concrete bases of its Nissen huts are still in the ground near the sewage treatment works, where the path takes an inland climb up a flight of steep steps. Some of the old barbed wire remains and the ground is uneven, so watch your footing if you go looking; the site is a stop on the Great Wars Trail. The village’s other modern claim: the actress Jessica Reynolds, who plays Caitlin in the Kneecap film, grew up here.
Walking the coastal path
The North Down Coastal Path runs 16 miles from Holywood to Orlock, near Donaghadee, and the Seahill section is a good short sample of it. The steep steps by the treatment works are the local landmark, an inland dip that lifts you briefly above the shore before dropping you back to the water. Underfoot the surface changes constantly: concrete, then stone, then grass, then rocky foreshore, so wear something with grip, especially after rain.
Out on the open water, this is a reliable spot for grey seals, which fish and haul out along this part of the lough. Where the path threads past houses it follows private roads, and access here rests on the goodwill of landowners rather than any public right of way, so give way to residential traffic and keep dogs close. Cyclists are asked to respect the Highway Code on those private stretches, where residents have right of way; it’s shared, courteous use rather than a ban.
One thing worth knowing before you build a plan around it: the much-discussed upgrade of this path is not happening on any firm timeline. In 2023 Ards and North Down Borough Council shelved its improvement plans after local opposition, so the steep steps, and the lack of a level, barrier-free alternative at Seahill, are likely to stay for the foreseeable future.
Getting there and the station
The train is the easiest way in. Seahill station, on the Belfast–Bangor line, opened in 1966 and sits a short walk from the path with step-free access to the platform. Set your expectations, though: there’s no car park, no ticket machine, no toilets and no staff, just some outdoor seating on a steep road, so buy your ticket before you travel. Trains reach Belfast in about 15 minutes and Bangor in about 10. Drivers come in off the A2, but on-street parking is tight during weekday commuter hours, and the village itself has next to nothing in the way of shops or cafés. Stock up in Holywood, one stop back down the line.
Along the coast
Head east and the path runs through Helen’s Bay into Crawfordsburn Country Park, with woodland trails, a sandy beach, and Grey Point Fort, a coastal-defence battery with views back across the lough towards Scotland on a clear day. The country park’s well-kept loops make it the better option if you want smoother, family-friendly walking away from the steps.
West of the village the Royal North of Ireland Yacht Club sits on the shore; the club is private, but its moorings are part of the view from the path. If you’ve only half an hour, walk east from the station towards Helen’s Bay and take the train home rather than retrace your steps. It’s the prettiest stretch, and the line is right there when the wind picks up.
