Oahu Dolphin Divers

Scuba and Snorkeling Tours from Waianae Harbor

The ONLY dive boat on the west side - from Ko Olina to Waianae

Cruise Ship View Our Tours



Oahu Dolphin Divers operates the only dive boat on the west side of the island. It departs from Waianae Small Boat Harbor on the island of Oahu. During the whale-watching season, which peaks from January to March, we also offer whale-watching excursions.

Oahu Dolphin Divers’ vessel, the South Seas II, is a 38’ Delta located in Waianae Small Boat Harbor. There is no physical office at the harbor. Guests will meet the boat in the harbor (parking is free) at the commercial loading dock.  To find that, you face the ocean and go to the far left side of the harbor.  For private tours of indeterminate start time, we may meet you at our slip on pier C.

Oahu Dolphin Divers is the primary dive boat of Honolulu Scuba Company located in Kaka’ako.  For the dive staff, the day begins and ends there, and it is possible to get a ride out to the dive boat by meeting the staff at the shop.  If you are staying in a Ko Olina Hotel (Ko Olina Marriot, Disney Aulani, or Four Seasons), we can also pick you up on the way to the boat.

The west side is the best side for scuba diving on Oahu. Because of the island’s trade wind weather coming out of the northeast, the west side of the island has the most consistent and calm oceans on the islands and the very best weather for ocean tours. But possibly more importantly, if you want to dive in lava tubes – who doesn’t? – then we are your best (and only) choice. There are three good wreck dives as well, and we dive with green sea turtles every day.

If you are staying in Ko Olina, it doesn’t make sense to fight traffic into town to go diving, snorkeling, or whale watching.  And if you are in Waikiki, it is worth the one-hour drive out to explore this beautiful coastline. From Waikiki, you are coming the opposite way of rush hour both morning and afternoon charters.


My husband and I had so much fun. The crew was friendly and knowledgeable of the area. Lovely easy snorkeling trip. Mahalo!

Didn't know what I was going to get, when I booked online before the trip, but as it turned out I couldn't have been happier. Great vibes, great memories! I highly recommend them.

Aloha! If you want a real Hawaiian experience I would recommend Dolphin Divers! The owner is super friendly, professional, knowledgeable and answered any questions we had. I rate them a 10 out of 10! My teenage kids had a blast too! Felt more like a Hawaiian adventure than the way the touristy activities make you feel. We’ll definitely be using them again. Mahalo Mike!
