The American side of the falls.
The Canadian horseshoe falls (with Maid of the Mist boat trip, we plan to do this).
It's so immense to look over the edge, photo's do the experience no justice. The water is so violent and powerful.

We did the Journey Behind the Falls walk. This is about 200 meters in, roughly a third the way round the horseshoe falls. The waterfall can be seen through portals like this one.
Niagara touristy bit of town in the daytime, loads of stuff to see.
