Bounce Below is a giant trampoline playground built inside a slate quarry cavern in the Welsh mining town of Blaenau Ffestiniog, developed by Zip World.
As part of their latest attraction, staff have transformed a slate cavern by installing three giant trampolines in caverns, ranging from 20 feet to 180 feet high.
Bounce Below will open in just a few weeks and will offer visitors a playful experience deep beneath the surface of the earth. Owner Sean Taylor said: ‘It’s a one hour activity where customers get dressed up in a cotton overall and given a helmet, they then jump on a train and travel inside the mountain.’
