Witness the brilliant colors of a sunrise over Diamond Head crater. Ideal for early birds, couples or families who are up at the crack of dawn during their Hawaiian vacation due to time zone changes. As we start out our tour from Alawa’i boat harbor towards Diamond Head alongside of the Waikiki coast, it will be a short boat ride to reach the Turtle Canyon snorkeling site. This spot is known for the large numbers of sea turtles that float above the reef while the reef fish swim around them and clean their shells. When the turtles come up to breath, they can even be seen by our guests relaxing on the boat! After our snorkeling adventure we head towards Diamond head, these early morning hours are the best chance to see the Hawaiian spinner dolphins playing and swimming around the boat.

Outrigger canoes first arrived in Hawaii around 200 AD, some large enough to hold up to 80 people, and were filled with essential items like edible plants, water and animals to ensure a somewhat safer voyage for the brave explorers who took off in search of land. Learning to surf an outrigger canoe is a right of passage for men and women of the sea, and it is an honor to do so in the Hawaiian islands where surfing gained a global foothold.
