These are walls of one "building"...the roof is a trellis with Wisteria covering it. The Wisteria is one of the pictures the dying batteries erased.
So sorry you lost some of your pictures. :'( This is an amazing waterfall, I'll bet it sounded beautiful, too.
I think the walls of water were my favorites. The sound of the water blocked out the people and airplane noises and made it a very pleasing place to be. We are going back in March for Spring in the Arboretum. The Wisteria will be gorgeous then.
Cripes, I don't know about you all but I can definitely hear the water from here. The lighting is just fantastic as well. Cheers Toni.
