Ruthin Castle in North Wales, UK, has revealed that The Moat - its all-weather spa concept incorporating indoor and outdoor experiences - is to open to guests on 1 August.

The new spa is nestled amid the woodlands of the privately-owned castle hotel's moat, with facilities including one of the UK's first outdoor log-fired sauna tents.

Owners Anthony and Amanda Saint Claire worked with Blue Spa and Leisure in designing the spa, a process which included researching Finnish, Siberian and Russian experiences.

More than £2m (US$3.1m, EUR2.6m) has been invested in The Moat, which will be open to both hotel residents and non-residents and will offer a range of spa days, breaks and packages.

A Dutch hot tub with seaweed and herbs, a fire pit for barbeques and a spring water shower fed by the Clywdian mountains are also among The Moat's exterior facilities.

Inside, the spa will contain spring water and mineral-rich hot tubs and a hot tub, along with five treatment rooms - one of which will be a VIP couples' room.

Treatments at The Moat will use products made exclusively for The Moat and will feature a range of ingredients sourced locally - such as Anglesey sea salts and sweet honey.

A spokesperson for Ruthin Castle said: "The Moat rests in the rustic woodlands of this ancient castle's moat and represents a new concept in luxury social spa experiences.
