The falls can be viewed from several angles, the view in the image is what 95% of the public sees. You can walk over to the top of the falls. Or take a trail around to the other side of the falls. You can not approach the falls from down river due to a choke point (visible from main view) in which the river flows between to sheer rock faces and plunges another 15feet or so, Lower Undine Falls. The lower falls requires a hike, plus a little, but easy to figure out, off trail hiking. It is an ankle twister getting the the bottom falls. If you wanted to get to the bottom of Undine falls, according to the park services office, you can climb down "IF" and that is a big if, you can keep off of anything that would be called a cliff face. It is a difficult and a bit risky to attempt since your going to be above, below, or between cliff faces, and I imagine there are plenty of tourist who would complain to Rangers, or decide they could do it...so if you must attempt it, wait till the off season, bring a friend, some rope, darn good shoes, and a helmet might not be a bad idea either. Keep safe.
