Si5 Spy Missions Norwich is an exciting indoor adventure centre located in Castle Quarter, Norwich, where children (and adults) become secret agents for the day. It offers immersive, story-based escape-style missions that combine puzzles, teamwork, and physical challenges in a thrilling secret-agent setting.

The experience includes climbing through laser mazes, cracking safes, venturing through vents, and solving computer-based puzzles to complete daring spy missions. Each session is guided by a personal mission leader, and the difficulty automatically adjusts based on players’ ages and abilities — making it suitable for kids, teens, and adults. For older visitors (14+), the Operation Covert Sword mission adds a more complex challenge involving stopping a rogue agent before a missile strike on London.

Pricing is £17.50 per person (up to 8 players), £16.00 each for 9 or more players (including food), or £14.00 for the mission only (2–24 players). Birthday parties are a highlight, with packages including a full spy adventure, food, and dedicated guides. 

Overall, Si5 Spy Missions Norwich is a must-visit for families and groups seeking indoor adventure and teamwork fun. With clever puzzles, cinematic storylines, and great value pricing, it’s one of the best interactive experiences in Norwich.
