The Halona Blowhole is a natural attraction on the southern coast of Oahu, Hawaii, caused by an underground lava tube. Visitors can view it from an observation deck and may also see whales, turtles, and outer islands. The nearby Halona Beach Cove is known for a famous movie scene, but caution is necessary due to dangerous conditions for diving and snorkeling.
The Halona Blowhole, sometimes spelled Halona Blow Hole, is a popular tourist destination in Hawaii. It is located on the southern coast of the island of Oahu, north of Haunama Bay along the Kalanianole Highway. Widely considered a must-see destination, a stop at the Halona Blowhole can be a great way to relax while visiting Hawaii.
The Halona Blowhole is a natural phenomenon, caused by an underground lava tube created by volcanic eruptions thousands of years ago. The lava tube that creates the Halona Blowhole opens into the sea, and as waves crash into it, tremendous pressure builds up inside the tube. This causes water to rise up and out of the pipe.
While water can splash up to 30 feet (nearly 10 meters) in the air, conditions aren’t always optimal for showcasing such an impressive display. If the waves are big, you are more likely to see this natural occurrence than on calm days. Otherwise, you’ll just see some mist and steam rising from the blowhole.
Visitors and locals alike recommend viewing the Halona Blowhole from the observation deck as it is dangerous to get too close. Reaching the belvedere is relatively easy for everyone as it is accessible to the handicapped. While the blowhole is beautiful, the water jet isn’t the only spectacular view you can see from the lookout.
From this vantage point during the winter, you can sometimes see whales at play. If the day is particularly clear, you can make out some of Hawaii’s outer islands, including Molokai and Lanai. Finally, if you’re particularly lucky, you might even get a glimpse of the Hawaiian green sea turtle.
The lookout is a good place to relax and bring a packed lunch. It’s also a nice walk to the beach. Next to the Halona Blowhole is Halona Beach Cove. You can swim here when the waves aren’t too rough, but as there are no lifeguards on duty, you may want to play it safe and refrain from doing so. Halona Beach Cove is also known for a famous scene between Burt Lancaster and Deborah Care in the 1953 film From Here to Eternity.
The coast where the blowhole is located is one of the most dangerous for diving and snorkelling because the high cliffs prevent you from getting out of the water easily. In addition, the strong current, slippery rocks and high waves make caution essential when visiting this beautiful location. It’s better to view and enjoy the Halona Blowhole from a safe distance than to put yourself in danger.
