Bounce Below is a series of slides and trampolines mounted up to 180 feet high on the walls of an abandoned slate mine. The attraction is located in Blaenau Ffestiniog, North Wales. On opening day, July 4, 2014, members of the public are invited to show up, descend into the mine via train, and amuse themselves with the net-protected trampolies as they enjoy a light show.
