Bounce Below or Zip World Slate Caverns are the names for underground theme parks located at the MineLlechwedd Slate Caverns. Obviously, the show mine didn't work very well as a tourist attraction, probably because there are so many show mines in Wales. So the operators equipped the mine with a zip line on the surface first. This seems to have worked, so they added an underground climbing, zip-line and net jumping experience in some of the huge chambers of the mine. And since this first underground experience was opened, two more were created. One is located at the nearby Penrhyn Slate Quarry near Bethseda, and one in the forest in Conwy Valley. All belong to what is now called Zip World, but as we are specialized on underground tourist sites, we list only Bounce Below.

All the tours at this place are climbing experiences, which include zip lines, jumping into nets and climbing on wooden poles, ladders and rope bridges. As a result, some physical fitness is required, the minimum size is 1.20 m, maximum weight is 120 kg. Minors are allowed, but they pay the same price and must be accompanied by adults, at least one per seven children. Children under 7 are generally not allowed. Appropriate clothes are necessary too, good shoes, and clothes which are suitable for sports. Security equipment, helmets and lamps are provided.
