World’s Largest Underground Trampoline Opens in Wales

The world’s largest underground trampoline opens today in an enormous cave in Wales in Britain.

It’s roughly the size of two basketball courts.

The three giant trampolines in Wales can hold 100 people at a time and are linked by vertigo-inducing slides and stairs. The chance to bounce underground costs $34.

Slides connecting the trampolines are fun to go down, but like at a ski resort without a ski lift, you have to put in some effort to get back to the top.

Safety helmets and overalls are obligatory and nine foot high mesh walls stop people from bouncing out. The tallest trampoline is 180 feet off the floor.

Just don’t look down.
