First things first. No waterslide at any waterpark will ever be the same again -- not after cascading down real waterfalls in the Dominican Republic. The waterfall escapade -- billed as 27 Waterfalls, though that's really a misnomer, as it's more like 12 waterfalls flowing into 27 pools of water -- is only one of a multitude of outdoor adventures offered by Iguana Mama, the ultimate outdoor tour operator in the Dominican Republic.
