Adrenaline junkies take on 100mph zip wire
A mile long zip wire - the longest in the Northern hemisphere - in Wales is offering adrenaline junkies rides of up to 100mph.
The Big Zipper, as it is aptly called, is strung 700ft in the air at an abandoned quarry in Snowdonia.
On a clear day riders are offered breathtaking views of the Isle of Man and Angelesey - if they dare keep their eyes open!
The wire itself directly crosses the lake at Penrhyn Quarry, once the largest slate quarry in the world, in Bethesda.
A ride on it forms the final part of a two-hour guided tour of the quarry, with visitors also given the option of trying out the slightly tamer 'Little Zipper'.
The zip wire was designed by Nick Moriarty, who co-owns the attraction with former marine and jungle warfare instructor Sean Taylor.
