Hawaiian Waters Waterpark, previously Hawaiian Falls, is a signature attraction for The Colony featuring action-packed fun for the entire family. Twist and turn down the Bonsai Pipeline, climb the 65-foot Aloha Tower and choose from the Waikiki Wipeout or the Flyin' Hawaiian or drop into the Hawaiian Halfpipe. Those looking to just relax can spend all day in the sun making a splash in the Oahu Bay wave pool, cool off at Kahuna Beach or drift along the Kona Kooler river. Open May through September.
