Wet'n'Wild Hawaii, Water park in Kapolei, Oahu, US.

Wet'n'Wild Hawaii is a water park in Kapolei on Oahu with over 25 water slides, multiple pools, and specially designed zones for kids and families. The facility spans roughly 29 acres and offers various sections with different activity levels for visitors of all ages.

Construction of the Hawaiian Waters Adventure Park began on October 6, 1998, funded by a $14 million investment from Waters of Kapolei, LLC, owned by dentist Jack Harrington and lawyer Brooks Cutter. The park opened on May 28, 1999, and drew 440,000 visitors in its first year. Village Roadshow Limited bought it for $27 million in 2008, and it was renamed Wet'n'Wild Hawaii in early 2009. CNL Lifestyle Properties acquired it in 2009, and Premier Parks, LLC took over operations for the 2014 season.

Ride names draw on places and figures of the islands: Waimea Whirl and Waianae Coasters refer to Oahu's Waimea and Waianae districts, while the wave pool is called Hawaiian Waters. The Keiki Kove children's area uses keiki, the Hawaiian word for child. The park opened in 1999 as Hawaiian Waters Adventure Park, and the name survives in that wave pool.

The park sits in Kapolei in the City and County of Honolulu on Oahu, on 29 acres with more than 25 rides and attractions. It is the only water park in the state of Hawaii. Island Adventure Golf, added in May 2007, has nine ADA-compliant holes among its 18, so part of the course is accessible to visitors with mobility needs.
