Portrush Adelphi – Northern Ireland, UK
Coastal colours, old-school character and a new lease of life on Northern Ireland’s spectacular Causeway Coast.
Why DNA Hotels Loves It
● Marine & Lawn has transformed a longstanding Portrush hotel into an intimate 34-room retreat without polishing away its old-fashioned seaside character.
● Tartan headboards, maritime paintings, dark timber and deep oceanic greens and blues give the rooms a strong sense of the Northern Irish coast.
● The Red Sail Room is the hotel’s social heart — part sophisticated dining room, part local bar, with Northern Irish ingredients and just enough Italian influence.
A Seaside Classic, Recut
Portrush doesn’t need much help with the scenery. Atlantic waves, huge skies, sandy beaches and some of the world’s most celebrated links courses already provide plenty of drama. So when Marine & Lawn took on the longstanding Adelphi, the clever move wasn’t to compete with any of it. It was to give the old hotel back its confidence. Following a year-long renovation, Portrush Adelphi reopened in 2025 as the sixth property in Marine & Lawn’s collection of hotels rooted in Britain’s great golfing landscapes. The result is smaller, smarter and more characterful: just 34 rooms, a handsome Victorian exterior and interiors that take their cues from the colours and traditions of the Causeway Coast.
Tartan, Timber and the Atlantic
There is something reassuringly old-school about the design. Bedrooms combine navy and bottle green with dark timber furniture, maritime paintings, traditional cable-knit throws and bold County Antrim tartan headboards. Bathrooms continue the palette with deep green tiles and Floris amenities, while details such as old rotary telephones add just enough eccentricity. It’s coastal design without the usual driftwood-and-whitewash shorthand. Instead, the atmosphere occasionally suggests a particularly stylish country house that has somehow ended up beside the Atlantic — warm, substantial and slightly nostalgic. And because there are only 34 rooms, the whole place retains the scale of a townhouse rather than a resort.
The Red Sail Room
The renovation really hits its stride downstairs. The Red Sail Room is a richly layered dining room and bar of maroon banquettes, white-painted timber, patterned wallpaper, glowing table lamps, greenery and suitably dramatic paintings of the sea. By lunchtime it can feel pleasantly subdued. Come evening, things change. Golfers return from Royal Portrush, walkers come in from the coast and locals arrive for drinks, filling the room with exactly the kind of life a small hotel restaurant needs. The cooking takes a loose Italian direction while remaining firmly attached to Northern Ireland: crab linguine, grilled fish, local mussels, steaks with salsa verde and ingredients sourced from the surrounding region. Then there’s whiskey. You’re close to Bushmills, after all.
Golf, But Not Just Golf
Marine & Lawn knows its audience. Royal Portrush Golf Club is roughly a mile away and hosted The Open Championship in 2025, while the hotel can help organise tee times, transport and even golf-club shipping. But reducing Portrush Adelphi to a golf hotel rather misses the point. Portrush has three sandy beaches, a harbour and the wonderfully nostalgic character of a proper Northern Irish seaside town. Beyond it stretches one of the most extraordinary coastal landscapes in Britain. The Giant’s Causeway and ruins of Dunluce Castle are nearby, as is Bushmills, while the Causeway Coastal Route offers miles of cliffs, dunes, beaches and walking trails. The hotel even has retro bicycles for exploring closer to home.
A Hotel That Belongs to Portrush
Perhaps the most appealing aspect of the Adelphi is that Marine & Lawn hasn’t attempted to turn it into an international luxury hotel that could exist anywhere. There’s polish, but also familiarity. The restaurant welcomes locals. The bar gets busy. Staff recommend walks and pubs, pack breakfast for guests who oversleep and discuss which Bushmills you ought to be drinking. That informality matters. Because however handsome the tartan headboards and velvet banquettes might be, this is still a small seaside hotel in Portrush. And it feels like one.
Why It Works
The new Portrush Adelphi finds its character somewhere between golf clubhouse, country house and classic coastal inn. Marine & Lawn has sharpened the design, improved the food and added enough sophistication to make the hotel feel special, without disconnecting it from the town outside. Come for Royal Portrush if you must. We’d stay for the dark-green rooms, crab linguine, a late Bushmills in the Red Sail Room and the Atlantic waiting at the end of the street.
