An abandoned mine in the Welsh Countryside seems more like the secret lair for a Bond villain than a destination for family fun. But, deep in the Llechwedd Slate Caverns, a 10,000 square foot cave twice the size of Bill Gates’ house, is Bounce Below, the world’s first-ever underground trampoline park. Yup, that’s correct: A trampoline park in an underground cave.
Bounce Below, located in northwestern Wales near the Snowdonia National Park, houses 6 massive netted trampolines suspended 20 to 180 feet above the cave floor. Each level is connected by an industrial slide the length of a double decker bus, and bathed in so much neon light you’ll feel like Steve Aoki decorated the place. Anyone afraid of the dark, heights, or small spaces should stay home. Anyone who wants bounce, flip, tumble, and slide in a former mine better book a flight.
The underground playground is run by Zip World, a company dedicated to bringing adventure tourism to North Wales. It opened in July 2014 after owner Sean Taylor decided to renovate the unused slate quarry after seeing a similar setup in France. Workers removed nearly 500 tons of rubble to make room for the trampolines.
The park is open year round. An hour of jumping costs 25 euros for adults or 20 euros for kids 7 and up. For younger kids (or older ones who are weak-kneed about the whole thing), there’s “Junior Bounce.” It’s i the same cavern as Bounce Below, costs just 5 euros, and is much less death-defying. Children between the ages of 7 and 12 years need supervision (lucky you!); children between the ages of 13 and 18 years need accompaniment by a spectating adult.
If the kids aren’t totally exhausted after bouncing 180 feet in the dark on technicolored nets, Zip World also has an underground Cavern Adventure as well. There you can experience the cave via zip lines, rope bridges, and rock climbing. It’s also home to an outdoor zip experience that lets you soar 6,500 feet in the air over the nearby Blaenau Ffestiniog cliffs and valleys. Because you can’t travel to Wales and spend all your time underground.
