Looking for one of the most dramatic natural attractions on Oʻahu? The Hālona Blowhole Lookout, located along the southeastern coast of Oʻahu, offers stunning ocean views, erupting seawater geysers and access to one of the island’s most scenic hidden beaches: Hālona Beach Cove, also known as Eternity Beach. The Hālona Blowhole lookout is free to visit with no entry fee or reservation required.
Here’s everything you need to know before visiting, including how to get there, the best time to see the blowhole and important safety tips.
The Hālona Blowhole is a powerful natural geyser formed thousands of years ago during volcanic eruptions. As molten lava flowed into the ocean, it created underwater lava tubes. Today, ocean waves force water through those tubes, causing dramatic sprays of seawater to shoot up to 30 feet in the air.
“Hālona” means “lookout” in Hawaiian — and this one lives up to its name.
The best time to see the blowhole is during the winter months (November through March), when high surf from the Ka‘iwi Channel produces the largest and most frequent water eruptions.
Height of geysers: Up to 30 feet
Whale season: December–April — great chance of spotting humpback whales
Safety warning: Never climb down to the blowhole. Powerful waves and slick rocks can be deadly. Always stay behind the guardrails and view from the designated lookout.
Just below the lookout lies Hālona Beach Cove, a small, sandy beach surrounded by lava cliffs. It’s one of Oʻahu’s most photographed secret beaches, known for its cinematic history and natural beauty.

“Pirates of the Caribbean”: “On Stranger Tides” (2011): Featured as “Whitecap Bay.”
Summer: Generally safe for swimming on calm days.
Winter: Often too dangerous due to strong waves and currents.
Access: Steep, rocky path from the lookout — wear sturdy shoes and watch your step.
Tip: No lifeguards are on duty. Use extreme caution and never swim during high surf.
Tucked into the back of Hālona Beach Cove is a lava tube cave, formed by ancient volcanic activity. It’s a fun spot to explore, but only when the ocean is calm. Bring a flashlight if you plan to enter and never enter the cave during high surf or rising tides. The area can flood quickly and become dangerous.
