Twin Creek Falls is a 115m waterfall that you can spot from the Arthur's Pass Highway not far from the Otira Viaduct. But it's usually overlooked as drivers motor their way through this Southern Alps traverse. Had it not been for Devil's Punchbowl Falls not much further to the south, this waterfall might have gotten its own signed car park as well as increased attention.
