at first i would of said no! and after reading the line of 'The most daring visitors jump in and allow themselves to be carried towards the falls at terrifying speed. They are just inches from the edge when the rock lip brings them to a halt as the raging waters of the Zambezi crash over the edge a few feet away.' id say definately not....
but after seeing that youtube video at the bottom - then yeh id do it - it doesnt seem as rough and terrifying as they make out as it seems so calm in that bit of the pool - although i defo wouldnt hang over to get a photo lol!!
