Halona Blowhole

The Halona Blowhole was formed thousands of years ago when volcanic eruptions sent molten lava flowing down and stopping abruptly when the hot liquid rock came in contact with the sea. As a result, beautiful and unusual rock formations were created and sometimes, molten lava tubes were produced from inside the caves that formed along the rocky shoreline. This is how the Halona Blowhole came into being as an amazing natural wonder.

Located on Oahu's south shore, just 15 minutes from Waikiki and north of Hanauma Bay, the Halona Blowhole is where locals and visitors go to watch the powerful ocean waves come crashing in and spray high up into the air through the lava tubes like a geyser. There are days when the blowhole is completely inactive, which can be disappointing for those who come to see it, so it's important to go on windy days during high tide, as this is when the sea performs its finest show.

To the right of the blowhole is Halona Beach Cove, a small, sandy beach and the location of the famous love scene between Burt Lancaster and Deborah Kerr in the 1953 movie From Here to Eternity. Below the blowhole is Kaiwi Channel, one of the most dangerous ocean channels in the world. On days when the surf is calm, you can walk down the steep rocks to the beach and enjoy a swim, but it's strongly advised to wear shoes and be watchful, as the sea is unpredictable and powerful in this narrow channel. It is best to view this scenic spot from the lookout, particularly on windy days.

The lookout offers a spectacular view of the coast and neighboring islands and during the winter months, many come to whale watch or see honu, the endangered Hawaiian green sea turtle.
