Local and tourists in Wales can now look forward to a new attraction: "Bounce Below" is the largest trampoline system underground.
It hangs in a cave, twice as big as St. Paul's Cathedral in London - and it is 111 metres high. Once they hit the cave, jumpers are treated to an extraordinary view: Three giant nets, securely attached to ropes are lit up by different coloured spotlights.
But here you definitely need a head for heights - the huge nets hang 5 to 54 metres high. Visitors with no fear now have the recently introduced option of switching from the different levels, at which the nets are attached, using four tube slides with a total length of 70 m.
These are attached to a pylon 20 m high and were fitted almost completely by hand by our fitters (no crane, only climbing equipment and winches).
