Halona Blowhole

Halona Blowhole is a rock formation and a blowhole on the island of Oahu, Hawaii off of Hanauma Bay at Hālona Point overlooking the Pacific Ocean. In Hawaiian hālona means “lookout”.

On windy days when the tide is high, the ocean breeze sends the waves rolling on to the shore where the rock formation then shoots sea spray high into the air through the cave acting like a geyser. It is not always at its best every day though. The blowhole is most active when the tide is high and the winds are strong.This is a big tourist spot in Hawaii. People come from all over to enjoy the beautiful scenery, the beach at the cove, and in the winter it is the spot to go to see the humpback whale as they take their journey leaving the North Pacific or the Honu (The Hawaiian Green Sea Turtles) swimming about. Diving is possible along the coast when there are light northerly winds blowing and no surf. It is recommended diving elsewhere when waves are breaking. The erratic tidal changes that take place offshore make the waters experience a strong current called Moloka’i Express that can drag divers out to sea. A large wedged shape area right off the coast next to the cove is a reef coated with Sinularia Leather Coral, which is a coral that does not need much light to live, in which you can find many different species like echinoderms, slugs, corals, and eels. The shoreline cliff beyond the cove, ending at a point, should be the limit of any shore diving here due to the strong current and distance. There is also a narrow rift along the base of the cliff which was formed by a large section of rock that broke away from the land can be seen very well on a clear day.

Hālona Cove

Hālona Cove is the small pit of sand just to the right of Hālona Blowhole (when facing the ocean) where tourists and locals can also enjoy a small beach while visiting the blowhole attraction and it is great for swimming when the surf is very calm. Access to the beach is difficult (most visitors scale the cliff from the parking lot) and it is dangerous to swim here while the surf is rough considering there are no lifeguards on duty here. This was the site of the famous love scene between Deborah Kerr and Burt Lancaster in the 1953 film From Here to Eternity, and also between Drew Barrymore and Adam Sandler in the movie 50 First Dates. In 2012, the beach was featured in the music video for Nicki Minaj’s “Starships”. The blowhole was the location for a scene in Jurassic World: Fallen Kingdom, in which the characters Owen, Claire and Franklin wash up on a beach.
