Si! Spa in West Kilbride has a sauna, an outdoor hydro pool and direct access to the beach

With its glassy waters, unspoiled coastline, rolling mountains and fresh Atlantic air, Scotland is already a prime place for rest and relaxation. Add in a spa and you’re guaranteed to emerge feeling more rejuvenated than ever.
Of course, Caledonia is already home to a vast collection of peaceful retreats. But, come one – can you really have too many? Last month, a brand new spa was added to its roster. The new Si! Spa in West Kilbride is tipped as ‘one of the most exciting leisure and tourism developments in Scotland for 2026’.
The wellness venue has six treatment rooms, a four-person Rasul (mud therapy) experience and an indoor thermal area with a steam room, showers and relaxation areas. Outside, looking over the Firth of Clyde and across to Ailsa Craig, there’s a large hydro pool, a sauna, a cold drench bucket, a fire pit and direct access to the beach. So, if you so wish, you can work up a sweat in the sauna then run down the sand to cool down in the water, and repeat.
It’s part of the £3 million expansion at the Waterside Hotel at West Kilbride, which is less than an hour from Glasgow. The enormous makeover also included the addition of 17 new guest rooms and a luxury suite with its own balcony and hot tub.
The brand new spa restaurant also offers a menu of healthy dishes like poke bowls or porridge alongside some more indulgent bites such as fries loaded with haggis, peppercorn cream and crispy fried onions or pulled pork, honey glazed bacon and cheddar.
A thermal experience at the spa starts at £45 per person for two hours of access to all of its facilities. There’s also the option to book a whole spa day or a multi-day spa break. You can plan your trip here.
