Avalanche Creek Falls is an attractive waterfall that you can see from Arthurs Pass Village near the start of the scenic Avalanche Peak Track. According to a DOC ranger, the falls are actually floodlit at night (bring a torch if you're doing this at night). We accidentally noticed this waterfall while exploring the Arthurs Pass Village.
