There is a not one but three gigantic underground trampolines located inside the Llechwedd caverns in Wales, and it looks amazing.
Appropriately named Bounce Below, people will be able to go trampolining in and old mining cavern which is twice the size of St. Paul's Cathedral.
Not only do they have 3 trampolines, they also have slides and suspended stairways that all interconnect with each other.
The biggest slide is an impressive 60 foot.
And if that wasn't awesome enough then the amazing lights that are used to light up the cave will blow your mind.
Who else wants to go here? We do!.
