One interesting spot near the falls is the Whtie Water Walk. You can walk along some of the world's strongest rapids, class 6. At this point in the river, the water is traveling about 30 mph. Many people have died trying to navigate this stretch of water.
We also went to the American side of the falls.
And went down to Cave of the Winds and walked along and over part of the American falls. We had on pants, which was a large mistake and anything our ponchos did not covered was drenched!
