Wet 'n' Wild Phoenix

The scorching Arizona sun beats down on Adobe Dam Regional Park, but visitors to Wet 'n' Wild Phoenix keep cool as they splash throughout more than 30 waterslides and attractions. The 35-acre facility is home to an abundance of adrenaline-pumping rides—including a towering tandem water coaster, a spiraling 45-foot funnel, and a four-story six-tube speedway—to contrast its more laid-back attractions, including an interactive playground and 700,000-gallon wave pool. The junior water park accommodates younger guests with kid-friendly funnels, rivers, and racing slides. Food and beverage carts traverse the grounds, while an onsite restaurant, cafes, and pubs fuel fun with full meals, snacks, and drinks. To ensure guest safety, a vigilant staff of lifeguards patrols the park and will swiftly kick out sharks who've shrewdly disguised themselves in bikinis and sun hats.

Although Wet 'n' Wild Phoenix sometimes features discounts, this Groupon still offers the best deal available.
