Coast & Country: World's biggest underground zip line

On Coast & Country tonight Nicola Hendy takes a ride on the biggest underground zip line in the world.

Go Below Underground Adventures in North Wales are among a number of companies who many say are reinventing the area as one of the biggest adventure sport destinations in Europe.

Far below the surface of Cwmorthin valley, at Betws y Coed, Go Below have installed a series of zip lines and abseils along miles of full height tunnels which are as breathtaking as the views above ground.

And with the world's biggest underground zip line at its heart, it’s an adrenaline-fuelled trip that many say is not to be missed.

As well as testing her nerve in the depths of the mountain Nicola also discovers more about the industrial past of the valley.

In South Wales Andrew returns to his roots on the beautiful Gower Peninsula where he runs bushcraft and survival skills courses.

Andrew gives us a tour of the woodland where he works and shares his top tips on the holy trinity of surviving in the great outdoors; shelter, fire and food.

Don’t miss Coast & Country tonight at 8.00pm on ITV Cymru Wales.
