Halona Blowhole is one of the well-known natural attractions on the island of Oahu facing the Pacific Ocean. The blowhole was formed by molten lava tubes from volcanic eruptions thousands of years ago at Halona Point. When the tide is high on a windy day, the ocean breeze sends the waves through the tubes and the water blows high in the air, sometimes as high as 30 metres. This natural occurrence was named the Halona Blowhole.
It wasn't the best time to observe this natural phenomenon during the day of my visit. The blowhole was just blowing smoke-like water vapours as can be seen at the right side of the photo below where there is just a small patch of smoke on the rock formation.
While waiting for another blow, I went around to look at the surrounding area.
I waited for a couple of minutes but there wasn't any blow. When the tour guide was making his last call, I gave up on the observation. Well, at least I had see a small blow.
I requested for another couple of minutes to look around again.
Just to the right of Halona Blowhole is Halona Cove which is a small pit of sand forming a leisure beach for the visitors. Getting down to the beach is not an easy feat as one has to climb down the cliffs. I think the effort was worthwhile for those people down there.
