It has also been given the designation as a Hawaii Scenic Byway called the "Royal Footsteps Along the Kona Coast".[17] This byway offers archaeological sites that have survived over hundreds of years. Kailua Pier is the starting and finishing point for the Ironman World Championship Triathlon in October.[18] North of the pier is the Kamakahonu royal residence and Ahuʻena Heiau. Another royal residence is Huliheʻe Palace, used by members of the Hawaiian royal family until 1914.[19] The Historic Kona Inn and other shops are on the street.
