O‘ahu, Hawaii, USA
Oahu: Hawaii Kai The nine-mile Hawaii Kai downwind run on Oahu’s South Shore is one of the main training grounds for downwind SUP enthusiasts—and a challenging one even for experts. This area has a long history of SUP and outrigger paddling, and provides a well-known stretch of “bumps” (ocean swell) that allow paddlers to maintain speed as they travel from Koko Head and Koko Crater past Black Point at Diamond Head. Just off the lighthouse, the swell steepens, delivering paddlers around the point as speedily as a water-borne rocket sled ride into Kaluahole Channel and the high rises of Waikiki. Watch out for the surfers!
