The Traitors is filmed at Ardross Castle, located in the Scottish Highlands. This 19th-century castle and its surrounding estate cover over 100 acres of parkland on the banks of the River Alness, about 30 miles north of Inverness. Ardross Castle serves as the main setting where contestants eat, socialize, and compete in challenges, some of which take place at nearby locations such as Loch Glass. The castle has a rich history with various notable owners and has been extensively renovated by the McTaggart family. It is not available for overnight stays like a hotel but can be booked for weddings and corporate events. The Traitors is the primary entertainment production filmed at Ardross Castle, making the location unique to the series.
