Somersworth is famous for plenty of things. Your team's poker faces will not be one of them. In plain terms: your team explores on foot and takes on spy missions together. Come for the city. Stay for the moment your most sensible teammate says yes to something bold, and everyone talks about it for the rest of the day. You will decode messages, photograph evidence, and keep a straight face in public. No experience needed. There may or may not be a double agent on your team. Step-free mapped paths all the way: 2.4 km, 4 stops and about 2.5 hours, at whatever pace your team likes. No guide, nothing to download. You head home with the photos, the in-jokes, and conclusive proof of whose poker face needs work. Who it's for: friends, couples and families with teens; and private groups, from bachelor and hen nights to work teams and active over-55s. Book a private game for 1 to 8 players on a date you choose; a team of one works too. Bigger groups play as several private teams.
