Giant Gate Falls is a pretty powerful waterfall seen on the last day of the Milford Track. It is probably the last major waterfall you'll see on the so-called "Finest Walk in the World." This one's hard to miss as its easily visible from a swing bridge that passes right before the falls. There is also an open-air lunch shelter nearby if you're looking for an opportunity to eat food and fight off sandflies and keas.
