Salt Spa at The Salthouse

What a visit looks like

The signature is the outdoor infinity pool: heated, set right on the clifftop, with the water's edge lining up against the sea so it looks as if the two run together. Around it sit two Scandinavian-style outdoor saunas and copper seaweed mineral bathing tubs. Step inside and the thermal suite carries on the theme — a vitality pool with floor-to-ceiling windows framing the coast, a sauna, a steam room, a gentler sanarium, and a Himalayan salt room lit warm amber. Experience showers and relaxation beds are there for the pauses in between. On top of the thermal facilities, a treatment menu takes in massages, facials, floatation therapy, seaweed mineral immersion and Rasul cleansing rituals, all using the GAIA natural skincare range. Full use of the facilities comes as part of a spa day or package rather than with a treatment on its own, so pick the option that suits when you book.

The story

A spa built for its view

The Salthouse Hotel opened in 2019 on the hill above Ballycastle, and made its name early as Northern Ireland's greenest hotel — carbon-conscious, powered by its own on-site wind turbine and solar array, and built to sit lightly on a spectacular stretch of the Causeway Coast. From the start the location did much of the work: the ground falls away toward the sea, and the horizon opens onto Rathlin Island, the great flat headland of Fair Head, the Glens of Antrim and, on a clear day, Scotland beyond.

The £5 million Salt Spa, unveiled in summer 2026, was the final phase of the hotel's transformation into a full wellness destination — and it was designed around that view. The outdoor infinity pool is set so its edge lines up with the sea, and the indoor vitality pool is wrapped in floor-to-ceiling glass so the coast is never far from sight. Around them sit the Scandinavian-style outdoor saunas, the copper seaweed bathing tubs and the amber-lit Himalayan salt room, drawing on local salts and seaweed. As the hotel's director put it, the idea was to let nature become part of the experience.

Because it is so new, some of the finer detail — exact prices, session lengths, what's bundled into each package — is still bedding in, so it's worth confirming the specifics when you book. What isn't in doubt is the setting: for a spa day with a genuinely extraordinary outlook, this is a fresh and much-anticipated addition to the north coast.
