River rafters among the best in the world

I was browsing all the reviews of Moab river rafters recently doing some statistics for one of my clients, and noticed how many reviews our rafting companies have (thousands) and the high ratings they get. That prompted me to look around the globe for other hot areas. Not many other locales get this much action.

Does anyone out there know if there’s a page I can find out the volume of rafting activity? That would be interesting!
