Boat tours vs shore snorkeling in Oahu
Waikiki boats reach Turtle Canyon in minutes and give the best odds of green sea turtles from a city start. Shore snorkeling at Waikiki, Hanauma Bay and Ko Olina is free or cheap and needs no boat, but you handle conditions yourself. On the North Shore, tours only make sense from about May to September, when Sharks Cove and the nearby beaches are calm. In winter, choose a south shore or west side tour instead. Hanauma Bay tours mainly solve reservations and transport.
Look. Don't touch.
Leave only bubbles.
