WHERE TO DO IT:

The zip-lining mecca for mountain-loving thrill-seekers has to be NORTH WALES’ Zip World. It has several locations (including the new Tower location in South Wales) but the headline attraction is Velocity 2 at Penrhyn Quarry near Bethesda, just outside the Snowdonia National Park. It’s supposed to be the fastest zip-line in the world, firing you through the air at over 100mph! zipworld.co.uk
