Hālona Blowhole Lookout: Oʻahu’s Natural Wonder & Film-Famous Beach
Looking for one of the most dramatic natural attractions on Oʻahu? The Hālona Blowhole Lookout 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.
Located along the southeastern coast of Oʻahu, this must-see stop along the Kalanianaʻole Highway offers both beauty and history. 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.
What Is the Hālona Blowhole?
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.
When to See the Hālona Blowhole in Action
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.
Hālona Beach Cove (Eternity Beach)
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.
Famous Movie Filming Location:
-
“From Here to Eternity” (1953): Burt Lancaster & Deborah Kerr’s iconic beach kiss scene.
-

Swimming & Safety:
-
Summer: Generally safe for swimming on calm days.

-
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.
Explore the Lava Tube Cave
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.
-
Never enter the cave during high surf or rising tides. The area can flood quickly and become dangerous.
