Kalanianaole Highway (Hwy 72)

Kalanianaʻole Highway wraps around the eastern tip of Oʻahu, and its stretch through the Kaiwi coast between Maunalua (Hawaiʻi Kai) and Waimānalo is designated the Maunalua-Makapuʻu Scenic Byway. Landmarks along the byway include Koko Crater, Hanauma Bay, Hālona Blowhole and Makapuʻu Lighthouse, and the State Legislature calls the Kaiwi coast the last wild and undeveloped coastal land in east Oʻahu, with mauka-to-makai views. The land along the byway is a patchwork of different owners, managers and jurisdictions. Hanauma Bay is closed every Monday and Tuesday; visitors who are not Hawaiʻi residents pay to enter, and reservations are highly recommended. City buses no longer go down into the bay, and the bus stops at the top, on the highway. Sandy Beach and Makapuʻu Beach have lifeguards every day, and the City lists both among the island's common shorebreak beaches, where shorebreak causes serious neck and spinal injuries to experienced and inexperienced bodysurfers alike. HDOT posts lane closures for state roads each week, updated on Friday afternoons, so check before you drive.
