I spent a whole day in the Niagara Falls area, on a sight-seeing tour.
The pictures will probably talk much for themselves, so just a few words:

View to the American side

And the Horse-shoe falls at the Canadian side.

The "Maid of the Mist" going in.

Magnificent!
I also have some pictures from the boat itself, and some more, but they're still in my camera.
Hope you've enjoyed the pictures.
