The Traitors season 4 was filmed in June 2025.

Quick Scoop

  • Season 4 of The Traitors (US) was shot in June 2025, several months before its January 8, 2026 premiere on Peacock.
  • The cast went to the Scottish Highlands for filming, continuing the show’s signature castle setting.
  • That means what you’re watching now was recorded about seven months before airing, so all the drama and blindsides were locked in long before fans started reacting online.

Timing In Context

  • Previous seasons also filmed in the summer and premiered in January, so season 4’s June 2025 production fits the same pattern.
  • Articles discussing season 4 highlighted that the show was already fully filmed by late 2025, with only the rollout schedule left to go.

Where It Was Filmed

  • Season 4 once again used Ardross Castle in the Scottish Highlands as its primary filming location, maintaining the dark, moody aesthetic the franchise is known for.
  • The isolation of the castle setting is a big part of the format, helping amplify paranoia and alliance-building among the reality-star-heavy cast.
