Arriving at an area notied for its outstanding natural beauty, it was a long climb to our choosen location on Slieve Croob, but well work the effort. Just a few hours before sunset, this was the stunning view as our presenters spoke of the source of the River Lagan. But this view is nothing to what we were able to uncover as the copter travels over the cliff edge to reveal a drop as the ground falls away hundreds of feet below us.

Time wasn't on our side during this session. As we filmed we watched the sea mist roll in across the low ground and toward the mournes - and us.
