I have been to these falls, and witnessed some kayakers going over the falls, which I thought was fool-hardy, but they seemed to do it just fine.
It is a beautiful spot.
However, just last weekend in the news a man died there after climbing over the safety barriers and then slipped into the water. His body was held under the falls for over a day before they could recover it.
Very sad, but they call it a “safety barrier” for a reason.
