For adventure travelers that have done their fair share of zip-lining through jungle canopies and down the sides of snowy mountains, a new zip-line course in North Wales offers a different territory through which to fly. In an ambitious re-imagining of what a natural landscape can become, zip-line experts Zip World recently turned the Llechwedd Slate Caverns just outside the town of Blaenau Ffestiniog into the home of the world’s longest fully underground zip-line course. After spending a year hand-clearing the slate caverns, last used for mining 200 years ago, Zip World re-opened them as Zip World Caverns, a high-adventure destination where visitors are taken on a three-hour, 10-line zip tour through the colorfully LED-lit mine chambers, including one so enormous that it could fit 75 double-decker buses.
Between lines are various other obstacles—rope bridges, balance beams, tunnels, and precipitous pathways—for visitors to navigate, secured throughout with a patented safety device specifically designed for Zip World. It’s certainly not for the faint of heart, and for those whose inner daredevil is less pronounced, there are alternative attractions as well. Bounce Below opened here last summer, a fellow Zip World–run course composed of trampolines suspended in different caverns. Or, for those who prefer to get their kicks in the daylight, Zip World Titan is located above-ground at the same spot, taking visitors down a course at speeds of up to 112 kilometers per hour.
