Halona Blowhole Lookout

Halona Blowhole Lookout is a roadside overlook on Kalanianaole Highway (Route 72) on the southeast coast of Oahu, Hawaii, between Hanauma Bay and Makapuu. A short walk from the parking area leads to cliff-top viewpoints over a lava-rock shelf, where waves push through a submerged tube and shoot seawater into the air through the blowhole. Offshore, the island of Molokai is sometimes visible across the channel on clear days, and the small cove below the lookout is often called Cockroach Cove or Eternity Beach. The frame is a dramatic seascape of black lava rock, white spray, and deep blue water. The overlook faces south-southeast, so morning light comes from the left and lights the cliffs and spray, while afternoon light moves behind the viewer and can flatten the scene. The best season for large blowhole spray is November to March, when north and south swells are larger and the surf is energetic; summer is calmer, with smaller spouts. A burst of spray is unpredictable, so photographers typically shoot bursts or video at high shutter speeds. The spot is a stop on many island tours, so crowds peak mid-morning through early afternoon, and arriving early gives more room at the railing and parking lot. Tripods are generally accepted when they do not block paths, but the wet, windy edge can make them unstable. Drones are restricted along this coast. There is no entry fee. Visitors should keep well back from the wet rocks, as waves have caused injuries along this shoreline. Restrooms are limited near the lookout, so facilities at Hanauma Bay or Sandy Beach are the nearest alternatives. Water should be carried from elsewhere.
