Epic Waters is a water park in Grand Prairie, USA. Is an incredible 80,000 square-foot indoor/outdoor, year-round waterpark peaked with a beautiful curved-style, retractable roof. The waterpark’s slide tower features eleven waterslides, three of which are “first of their kind” in the waterpark industry. The best ride here is Lassoloop. Other rides which I recommend you try are YellowJacket Drop, Aquanaut, Texastwist and Prairie Plunge.
