The Wire is one of the UK's longest, tallest and fastest zip slides, running the 700 metre length of the NDAC Quarry in Chepstow. Launch yourself from the 70m high cliff edge and speed along the length of our 80m deep flooded quarry. Reaching speeds up to 40 miles per hour this exhilarating ride will take your breath away! New for 2020 we have two additional zip wires installed at the site, so now four of your family and friends can enjoy the Wire Zip Slide together!
