Halona Blowhole is an awesome sight to behold on the windward side of the island—you may have to be patient but the water can shoot up to 20 feet into the air!
The turn is right off Kalanianaole Hwy in Hawaii Kai and there is a decent parking lot that is usually guarded by a police officer.
The Halona Blowhole can be seen from the northeastern end of the parking lot where you can be perfectly situated to see from above.
The impressiveness of the blowhole may depend on the waves that day, but be patient! Every time I have gone I’ve seen awesome shows of force and mother nature.
This spot can either be a quick stop to see the blowhole or you could spend hours at the great beach below and exploring the lava tube.
At the south end of the lot you can descend to the Halona Beach Cove, which is a great little beach protected by high rocks in a half circle.
The waves here can get extremely high and dangerous so be careful!
This is definitely not a beach for kids to play in the water. The tide is strong and the waves crash violently against sharp lava rock. If you do decide to venture out, do not go very far out or you’ll risk being slammed against the rocks.
Now that we got the warnings out of the way, the beach is great to relax at and is for sure one of the most unique beaches on Oahu.
Once at the beach if you climb the rocks on the left side of the cove you can make your way around to be at ground level with the blowhole. It’s a spectacular view!
Before you go, pay close attention to the waves and the tide as this could be very dangerous. The rocks are super sharp and the waves crash and spill over to the path.
Halona Lava Tube
At the back of the beach there is also a small lava tube.

It’s kind of creepy and filled with cockroaches hanging out on the walls, but still pretty cool to check out.
I’m not positive how far it goes back but we went about 50 feet and then turned back.
There are various lava tubes on the Hawaiian islands–one of my favorites is on the big island called Nāhuku – Thurston Lava Tube. The short walk through the jungle is gorgeous and makes you feel like you’re Indiana Jones.
