Halona Blowhole & Cove is a gorgeous rock formation and blowhole on the island of Oahu. It’s one of Hawaii’s natural wonders and was created thousands of years ago when molten lava tubes were formed from volcanic eruptions.
This area overlooks some of Oahu’s most dangerous and violent waters. So when the Ka’iwi channel is churning during the winter months, strong currents and waves shoot water into the lava tubes below sending geysers as high as 30 feet out through the blowhole. (Please be careful if visiting here with little ones. The waters outside the cove are very dangerous as well as the area around the blowhole. Many accidents have happened here so pay attention to the warning signs & watch your kids closely!)
From the lookout point around Halona Blowhole, you can see miles and miles of gorgeous coastline.
Just below the blowhole and lookout area is Halona Cove. This is one of Hawaii’s most iconic beaches, and once you go you’ll recognize it in all kinds of movies (including the new Jurassic Park). The water here can be unpredictable and violent in the winter, so be aware of that if you decide to visit. You’ll also have to climb down some steep rocks to get to it.
There is a reef in the cove covered with Sinularia Leather Coral. You’ll also be able to find Hermit Crabs, Clams, Eels and a variety of fish. On a good day, you might also run into a sea turtle.
During whale season (December – April) there’s also a good chance you will see whales breaching here.
There’s a lava tube (cave) on the wall behind Halona Cove that travels under the road into the side of the mountain. Bring a flashlight if you want to explore (we didn’t go in) and be sure to go on a calm day when the waves aren’t high.
The drive to Halona Cove is incredible. To get there you’ll drive along the Kalaniana‘ole Highway that takes you along the coastline past Hanauma Bay and Kokohead Crater. The drive itself is worth the trip!
Just before reaching the overlook, you’ll find a small statue of Quan Am Nam Hai, or the Guardian of the Sea. She is a female goddess surrounded by flowers and offerings from her worshipers.
