Ka Iwi (Makapu'u Point) Professional Review and Guide
"This popular hike offers some of the best sea views on O’ahu, a photogenic lighthouse, and a special bonus from December through April: migrating humpback whales, lots of them, just offshore. It’s the easternmost point of O’ahu, affording views southwest back to Koko Crater and Koko Head, and northwest along Waimanalo Bay and out over several islands protected as sanctuaries for seabirds.
This walk is sunny and shadeless, but open to the sea breeze. Take water and sunscreen. Take binoculars too, if you have them. Start the gentle climb up a hill covered with koa haole, kiawe (mesquite), and prickly pear cactus, enjoying ever-improving views back toward the rocky coastline toward Koko Head. If you are here between December and April and notice an excited group staring out to sea, you can bet you’ll see humpback whales blowing, breaching, and doing whale things."
