Kalanianaole Highway (Hwy 72)

Kalanianaole Highway stretches 25 miles along Oahu's southeastern coast, connecting Honolulu to the windward side through dramatic volcanic cliffs and turquoise bays. This winding two-lane road hugs the coastline, providing constant ocean views and access to premier snorkeling spots including Hanauma Bay and Sandy Beach. Plan two to three hours for the complete drive if you stop frequently for photos and beach visits. The road gets congested on weekends when locals head to favorite fishing spots and beaches, so weekday morning drives between 7-10 AM offer the best experience with optimal lighting and cooler temperatures. Afternoon trade winds create blustery conditions, particularly around Sandy Beach and Makapuu Point. Parking situations vary significantly by location. Hanauma Bay requires advance online reservations and charges $25 admission for non-residents. Most beach parks and scenic overlooks provide free parking, though spaces disappear quickly after 9 AM on weekends. The Makapuu Lighthouse Trail parking area reaches capacity by mid-morning year-round. Bring sunscreen, water, and a hat since scenic pullouts lack shade. Drive cautiously around the numerous curves between Koko Head and Makapuu Point, watching for cyclists and pedestrians at popular stops. The gentle terrain requires no special hiking skills, though some viewpoints involve short walks on uneven volcanic rock. Several beaches along this route feature dangerous shore breaks and strong currents. Winter months from November through March bring larger swells that create hazardous ocean conditions at exposed beaches like Sandy Beach and Makapuu Beach Park. Check current surf reports before entering any water.
