Just saw this photo up on the home page & was about to click elsewhere when I thought, "Hang on, I know where that is. I've been there years ago!"
Yep Loch Ard Gorge - a ship, the 'Loch Ard' sank somewhere nearby back in the 1800s and of all those on board only 2 survived - a young man called Tom something and a young woman that he saved. No idea how they safely found their way through that gap!
