Though most fishing boats use Honokohau Harbor, this pier dating from 1918 is still a hub of ocean activity. Outrigger canoe teams practice and boats shuttle cruise ship passengers to and from Kailua-Kona here, and tour boats depart from these docks most days. Along the seawall children and old-timers cast their lines daily, careful not to hook the pair of sea turtles nesting nearby. For youngsters, a bamboo pole and hook are easy to come by, and plenty of locals are willing to give pointers. Each October close to 1,500 international athletes swim 2.4 mi from the pier to begin the internationally famous Ironman World Championship triathlon competition.
