What (and where) is the most beautiful waterfall you have ever seen (in person)?

For me, it is a toss-up between Rainbow Falls in the Adirondack Mtns (150' Bridal Veil fall down the side of a mountain), and Chilasco in the cloud forests of Guatemala (1000' flume in 2 parts in a remote section of Baja Verapaz). Just curious what you have seen and enjoyed!
