Halona Blowhole Lookout

Halona Blowhole Lookout is a scenic roadside stop on O‘ahu’s southeastern coast where you can watch waves surge through a lava tube and sometimes shoot seawater high into the air. The lookout also offers wide views of the Pacific, rugged shoreline, and nearby coves, making it a classic place for a quick photo stop or a short break along the Kalaniana‘ole Highway. It’s especially appealing when the ocean is active, but even on calmer days the dramatic coastal setting is worth the stop.

History

The lookout sits near Halona Point, a volcanic coastal area shaped by ancient lava flows and ongoing wave erosion. The name Halona is commonly associated with the area’s natural blowhole and the surrounding shoreline, which has long been a notable landmark on O‘ahu’s windward side.

Expert notes

• Roadside parking can be limited, so expect a short walk from the lot to the viewpoint.
• There is little shade and strong sun exposure, so bring water, sunscreen, and a hat.
• Keep a close eye on children and avoid getting near wet rocks or the cliff edge.
• The lookout is best treated as a brief stop rather than a long hike or beach day.
