    “Life changing!! Would do it again in a heartbeat. He vdeo my finance and I got taken of us by Tim was stelar; amazing quality and looked straight out of a movie. It was really nice of Kai the captain to stop ad let us watch he spinning dolphins we saw on our way to he dive spot. Meg and Makaela helped everyone feel super safe in the water as well. We never felt unsafe :) Great crew, wonderful experience, recommend to people of all ages!!

    Highly highly recommend Deep Blue! Let’s start with the sharks…we saw over 10 sharks (3 different types!) and they were AMAZING! So beautiful and such a humbling experience being in another predators territory. Next…the crew! The crew was so knowledgeable and made everyone in our tour feel safe.

    I’ve travelled all over the world and this is experience is up there for my favorite.

    Love the business Deep Blu has built and advise anyone visiting the North Shore to book.

    I cannot say enough great things about deep blue eco tours. The crew made sure everyone felt comfortable with this experience. Both divers in the water made sure we were okay and safe in the water! They were very informative and insightful. You can tell they are very passionate about what they do and love teaching others as well as sharing a once in a lifetime experience with others! Seeing and swimming with these beautiful creatures is something I’ll never forget.

    This was sooooooo cool! I was nervous but the crew made me feel very safe and we learned about the sharks and conversation! Nika was an amazing photographer! I loved every second of this tour.

    This review is overdue and I’m so over the moon that we decided to do the shark diving tour! Our captain was Kai, Tyler was our safety instructor & Nika was our photographer. M and my bf met Gavin n Newport Beach California on whim when we were both ona whale watching tour. By chance we ended up fining out he shark dives with Deep blue eco tours right around the time we were booking our Hawaii trip. If it weren’t for Gavin we would have never booked such an amazing excursion!! The team on our boat made us feel comfortable and educated us on safety before e got in. Nika was so wonderful and took the most incredible shots! I didn’t expect them to come out as good as they did. Tyler was funny and even helped me get incredible GoPro footage that I’ll get keep forever from that day! Our captain was also amazing ad even got in the water for a bit. We couldn’t have had a better day and experience. I’m recommending this to everyone I know.
