Formerly called the Hawaiian Waters Adventure Park, kids love this 29-acre water-theme amusement park, which opened in 1999 with some $14 million in attractions. Plan to spend the day. Highlights are a football-field-size wave pool for bodysurfing, two 65-foot-high free-fall slides, two water-toboggan bullet slides, inner-tube slides, body-flume slides, a continuous river for floating inner tubes, and separate pools for adults, teens, and children. In addition, there are restaurants, Hawaiian performances, and shops.
