Ko Olina Ocean Adventures

With over 22 years in operation of offering daily half-day snorkel tours, we at Ko Olina Ocean Adventures are your one stop shop for Water Adventure Enthusiasts! Whether it be offering a unique in water dolphin experience and a snorkel adventure tour on our motor boats on our DOLPHIN SNORKEL TOUR, or a sailing, Snuba, and snorkel package on our gorgeous double hull catamaran on the CATAMARN SNORKEL AND SAIL excursion, we have the boats, the crew and incredible clear tropical waters to deliver to guests the best snorkeling O’ahu has to offer!

Our leeward tours are very boutique and cater to those who want an incredible multi-snorkel site adventure. The owners of Ko Olina Ocean Adventures express their love of the ocean through limiting group sizes, providing premium snorkel equipment, training top notch staff, and of course, carefully choosing unique sites that showcase the natural marine beauty that is unique to our Hawaiian waters.

Let’s not forget what the main attraction of course is: Dolphins! We are fortunate to have a pod of about 200 dolphins that live along our western coastline, which we get to have an encounter with about 90% of the year. The dolphins rest and play on our coast and can be sighted jumping, splashing or swimming along our hulls. Also, in the winter months, our relatively warm coastlines are the birthing place of the Pacific Humpback Whales that can also be sited on our regular tours. Breaches, tail slaps, or surfacing are common Whale behaviors guests can enjoy sighting. Ko Olina Ocean Adventures’ naturalists help educate our guests with their trained knowledge on dolphin, whale and sea turtle behavior while our hydrophones allow guests to hear the songs and sounds of the sea.

At Ko Olina Ocean Adventures, we strive to help visitors of our island to enjoy and appreciate our coastlines’ unique features while sharing and passing on the spirit of adventure and Aloha.
