What to Expect: Submarine Tour in Oahu
Picture this—an actual Coast Guard-certified, 48-passenger submarine descending below the cobalt-blue waters off Waikiki. This isn’t just windows and waves. It’s 100 feet below the surface, through untouched reefs and historic wrecks, all while dry, comfy, and surrounded by fellow explorers.
The waters here are crystal-clear on most days, with visibility stretching out 70–100 feet, making Oahu one of the best islands in Hawaii for undersea touring. You’ll glide past purpose-sunk ships and airplanes that have become living reefs, buzzing with schools of tropical fish, eels, and maybe even passing turtles or reef sharks.
This is full-on explorer territory. The experience lasts about 45 minutes underwater—plenty of time to snag mind-blowing photos and spot marine life you’d never see from the beach. And trust me, watching a sunken airplane slowly appear out of the blue? It’s pure cinematic gold.
3 Pro Tips from Kai
Grab a seat near the porthole early
Trust the seasoned adventurer in me—porthole spots closest to the front fill fast, and they offer the most uninterrupted views. Scope out your position right when you board.
Don’t miss the surface transfer boat
You’ll take a separate shuttle boat to reach the submarine dive site. That ride is part of the fun, with panoramic Waikiki views and salty air pumping up the thrill factor before the descent even begins.
Go morning for max visibility
Ocean clarity is usually best before noon. Book the earlier slots if you want that mind-blowing contrast of reef color and insane visibility through the glass.
Who Should Book This?
This one’s perfect for adrenaline lovers, underwater dreamers, and anyone wanting to see Oahu’s depths—without getting wet.
