Hawaiian Waters Adventure Park

When the temperatures climb and the kids have had enough sand in their suits, head to this exciting water park. Spread across 25 acres are a wealth of fun-filled activities, including open-air and enclosed water slides (some that drop seven stories!), wave pools, a tubing river, and a water park intended solely for children. You'll also find a volleyball court, arcade, cafe, food court, gift shop, and even a spa catering to adults, complete with whirlpools and cool drinks. There's even a bar serving cocktails so adults can relax and unwind. About a 40-minute drive west of Waikiki and an outlet mall and other shopping are nearby.
