Island Splash Tours

Island Splash Tours takes you out to Turtle Canyon reef off the Waikiki coastline for an up-close snorkeling experience with Hawaiian green sea turtles — and they actually guarantee you'll see them. The 1-hour 40-minute tour fits up to 49 people on a brand-new boat, with options ranging from a classic snorkel trip to a sunset cruise or a private charter. It's one of those rare spots where the wildlife encounter feels genuinely wild, not staged.
