They film The Traitors at Ardross Castle in the Scottish Highlands, near Inverness in northern Scotland.

Main filming location

  • The UK and US versions of The Traitors are primarily filmed at Ardross Castle , a 19th‑century baronial castle on the River Alness, about 25 miles north of Inverness.
  • The estate has over 100 acres of grounds, which are used for outdoor challenges, moody night shots, and dramatic arrivals and departures.

Extra spots you sometimes see

  • Nearby Highland scenery is used for missions and atmospheric shots, including locations around Loch Glass and the wider Ardross estate.
  • Some international spin‑offs (like the Australian version) use different country locations, but the flagship UK and US editions are closely associated with this Scottish castle.

Behind‑the‑scenes logistics

  • The castle largely acts as a self‑contained “studio,” with cameras and sets built into rooms such as the Round Table chamber and meeting nooks.
  • Contestants are reported to stay off‑site in hotels around Inverness, with the castle reserved for filming to preserve its mysterious and cinematic feel.
