Ko Olina Ocean Adventures is your passage to the finest Snorkeling and Dolphin Encounter Adventure Tours on Oahu, Hawaii. Swimming with dolphins in Hawaii is an unforgettable, once in a lifetime experience. In addition to your in-water wild dolphin encounter, you will snorkel among breathtakingly beautiful coral reefs, rainbows of colorful reef fish and friendly green sea turtles that inhabit Oahu’s pristine ocean waters. The pictures below are just a taste of what you can expect on your Oahu dolphin encounter and snorkeling adventure tour!

Swimming with Dolphins
Hawaii’s ancestors held a deep and profound respect for dolphins, or nai’a. It’s a tradition the captains and crew at Ko Olina Ocean Adventures continue to honor and preserve, allowing our visitors to passively view the dolphins, but with a policy of no touching, and no loud or disruptive behavior. Our swim with dolphins procedure is to have our snorkelers assume a passive float position. The longer you hold perfectly still, the longer your dolphin encounter will last. Experience Oahu’s wild spinner dolphins in the Hawaiian tradition of respect for these beautiful animals.

Swimming with fish at KoOlina
Captain Todd and Captain Mick were some of the first to pioneer safe and non-intrusive dolphin encounters and whale watching with these wonderful ocean creatures. They now count 14 years in operation, with thousands of amazed, happy and repeat customers attesting to their success. They, and the rest of our captains and crew, continue Ko Olina Ocean Adventure’s tradition in providing Hawaii’s visitors with an adventurous, fun, memorable and safe ocean experience. It’s an Oahu snorkeling tour you can’t miss!

Being in a submarine and descending to 100 feet underwater is an adventure in itself. You will also get to see real marine life up close. The Atlantis Waikiki dive site is home to many Hawaiian fishes, coral, and turtles. Known for its quality and safety, Atlantis is an eye-opening experience that takes you beyond the classroom as you learn about coral, reef life and submersibles while visiting our sunken shipwrecks, airplane and other artificial reefs. Atlantis has a spacious air-conditioned interior, large view ports and comfortable seating. If you haven’t been to the bottom of the ocean before, this tour is a "must do!"
