“Diving with US Navy SEALs is to dive with the absolute best of the best. The attention to detail these guys have in every aspect of the experience for every person they take out, is unmatched in the industry.”

- Alex O’Loughlin, star of Hawaii 5-0


What We Do


Picture this: You're swimming in crystal clear waters above vibrant reefs and abundant ocean life—maybe next to a spinner dolphin, turtle, or humpback whale. Maybe you'll scuba dive, maybe you'll snorkel. Either way, you'll be discovering the incredible world beneath the waves, and we’ll be here to guide you with every kick and paddle along the way.


Scuba Diving Excursions

Join us as we explore many local West Side Oahu dive sites. Trident Adventures dive charters are catered for SCUBA divers of all skill levels. Come see why the Waianae West Coast is regarded as the best diving on Oahu, and in Hawaii. No Dive experience, no problem. Sign up for Discover Scuba Diver, and dive without any certification with a seasoned instructor. 

Freediver and Snorkel Excursions

Join us in the morning or afternoon to search for sea turtles and spinner dolphins as we cruise down the beautiful Waianae coastline. Occasionally we’ll find larger, rare marine life, and, during whale season, we often see humpback whales. Trident Adventures offers a unique option of becoming a PADI certified Freediver, a worldwide recognized certification!

Stephen Kaplan - Owner/PADI Instructor

Steve is a recently retired Navy SEAL and all around ocean lover. He spent the last 4 years as the lead diving instructor for the SEAL Team based here in Hawaii. As a veteran of many foreign wars, Steve’s unique prospect, value for life, and wonder for the aquatic world is unavoidably contagious. Out of all the extreme venues life has to offer, from skydiving to gun shooting, mountaineering, explosives, combatives, etc.., there is nothing that matches the dichotomy of excitement balanced with serenity that diving has to offer. There’s something to be said about the peace of mind knowing Steve brings the safest, and yet the most trilling underwater experience to Trident Adventures like none other.

Famed explorer Jacques Cousteau once said, "The best way to observe a fish is to become a fish." Learning to scuba dive opens up an entirely new world, and there’s no one better to train with than us. Our relationship with the ocean as former Frogmen is completely unparalleled, and you can rest assured that getting your certification with us is both safe and fun.

“My first experiences scuba diving were with Steve and Jimmy. Never done it before, zero experience. All fear disappeared knowing I was diving with two decorated Navy SEALs. The attention to detail in terms of checking gear and making sure that we were moving at a pace I was comfortable with made an individual like me with no experience feel super safe!

Never at any moment did I feel danger, and because of that amazing experience, I’m now addicted to scuba diving and can’t get enough of it!”

- Beulah Koele, star of Hawaii 5-0
