Escape rooms
Indoors, no fitness needed, works for 2-20 people, and everyone contributes something. Five minutes from Snow Hill Station.
Make a day of it
Pair a room with lunch in the Jewellery Quarter, a walk along the canals at Brindleyplace, or an evening on Colmore Row.
Planning tips
Book the activity first - good slots go early on Saturdays. Split big groups into teams of four to six for the best balance.
