It may be named after a desert and be located in the middle of Ohio with a population of just 78,000 people, but this city has the country’s largest waterpark – 173,000 square feet. You may think you’re in Africa when you’re inside because you’ll be surrounded by masks, tribal artifacts and wild animals’ sculptures. You’ll be riding 5-foot waves, sliding on a zip coaster, which offers speedy hikes and scary drops. Little kids prefer the Wild Kingdom because it has net crawls, plenty of water guns and a lot of small slides.
