Dive the Kona Coast on the Big Island of Hawaii with Ocean Eco Tours. Our tours are designed to be safe, fun, and educational.
Experience giant manta rays, indigenous marine life, mountains of intact coral ecosystems, and excellent 100-foot visibility in calm, crystal-clear water! Diving on the Big Island of Hawaii is among the best in the world.
We allow six divers maximum aboard our 30-foot dive boat, ensuring comfort and plenty of shade for all. The Nai’a Kai is well equipped with a 200 HP 4-stroke Yamaha Motor, allowing us to arrive at our local dive sites quickly, giving you maximum bottom-time.
Harbor Dive Center’s professional, friendly staff is committed to your needs and the environment. All of our guided tours, instructional courses, and charters have a minimal impact on the environment. We cater to smaller groups, allowing for a more personal experience.
We at Ocean Eco Tours are proud teachers of the sea and love what we do. It is our gift to you to share our knowledge and skills. All our staff (instructors and captains) are trained watermen/women who have dedicated their lives to the ocean and Her treasures.
Our eco-team members are well-educated about the ocean and its inhabitants, including the colorful corals, rays, sharks, dolphins, and seasonal humpback whales. Our onboard library is fun to look at before, during, and after dives, allowing you to learn about what you see, making your Hawaiian holiday a memory that will last a lifetime.
There are hundreds of breathtaking dive sites along the Kona Coast. Whether you are a beginner who has always dreamed about experiencing the underwater world or an advanced diver, Harbor Dive Center is ready to be of service. Long lava tubes and ornate caves created by volcanoes, swim-thru arches and coral gardens, and walls all lend their charms, adding up to Kona Hawaii’s unique topographical diving environment.
