The Llechwedd Slate Caverns located in Wales is the new home to one of the coolest, and most likely terrifying, adventure activities. Bounce Below is the world’s first underground, trampoline park.
To reach the playground, visitors must board a train which will take them deep into the caverns. Once they arrive at their destination, an incredible display of lights and a collection of 3 trampolines will be waiting for them. They have been set at varying heights; 20 foot, 60 foot and 180 foot levels which are connected by a series of stairways and slides.
