It's not what you would normally expect to see as you enter a cave in north Wales, but now Llechwedd Slate Caverns is home to the world's biggest trampoline.

Up to 100 people can bounce on this trampoline at any one time and at some points the brave participants will find themselves bouncing 80ft above the ground.

The trampoline has taken 4,500 man hours to build in a cave which measures 100ft by 60ft.

Many local companies provided the infrastructure for this record breaking trampoline which will be open all year around and hopes to attract all ages to give it a go.

The surreal experience of Bounce Below cannot be matched as there’s nothing like it anywhere else on earth. It’s essentially a ginormous underground playground and an amazing way to experience a subterranean world in a way never before possible."
