This Incoming Tropical Vegan Cart Wants to Raise Awareness for Ocean Conservation | Eater Portland

"A snorkeling company, One Ocean Diving offers opportunities to swim with sharks and other marine life in their natural habitat; Lamberson spent time working and free-diving with sharks there, created educational content from those experiences, and credits that work and her marine-biology background with shaping her veganism and conservation-focused approach for Sharks Cove." - Waz Wu

Best trip ever! Seeing the tiger sharks was just the icing on the cake! Our crew was Captain Liko, Faith, Marcus and Kaitlyn. They were great. I enjoyed the education prior to getting in the water! We got to see a ton of sharks and even got to dive close to some of them! So cool! Best experience and once in a lifetime! Would highly recommend this group! Side note: they offer skid shirts and go pro handles should you need them! This is included. They can also get photos of you but you need to request them ahead of time with the office.

We are incredibly happy that we got to take part in swimming with sharks! Of course, we had some reservations at first – it’s not something you do every day. But the moment we slipped into the water, any trace of fear simply vanished. At no point did we ever feel unsafe. The safety divers did an excellent job – professional, attentive, and reassuring throughout. The information shared before and after the snorkeling was also fascinating and full of interesting insights. The absolute highlight of the experience was a magnificent tiger shark that appeared right at the beginning – a moment we will never forget. If we ever find ourselves back on Oʻahu, we would definitely do it again. Our hearts now beat a little stronger for these fascinating creatures – and for all the other wonderful beings we share this planet with.

What an amazing experience! I love sharks and love snorkeling. From booking the trip, to their responsiveness via text, check-in all seamless. Gina and Kaitlyn our safety divers, were passionate and informative and helped to make a relaxed but fun boat ride out to the dive spot. In the water you can tell they take their job seriously, not only keeping everyone safe but prioritizing the shark’s safety, comfort and wellbeing. I am definitely booking again. The 7am tour made it so the water was calm and smooth. The blue of the water and visibility was unreal. The stars of the show were the 2 Tiger sharks we saw and the dozens of Galapagos sharks. Thank you so much!

This was the best experience of my entire life. I booked this tour at the end of my Hawaii trip to end my vacation with a highlight and this was by far the most beautiful thing I’ve ever done. I’ve been following Oceans and Juans work for a couple of years and it’s so inspirational and important what they are doing for sharks! With Gina and Faith we’ve had some amazing safety divers. They were so kind and told us many interesting facts and things to know about sharks. Some of these were really sad when they told us that over 100 million sharks are killed every single year! They also answered everybody’s questions and made us feel so safe in the water! My safety diver was Gina and she took some incredible GoPro videos of my dive and I couldn’t be happier with how they turned out. I also booked to photo package and my photographer Andrew did everything to get me into good spots for some amazing photos. This experience whole experience made me so happy that I came back for another dive two days later! Thank you to the entire team! I hope that many, many people will go on this tour because it will change your life and your perspective on sharks! Sharks are such important creatures for our ecosystem and they need protection! I feels so incredibly lucky that I got to see them in their natural environment.

I can't stop telling everyone about all the fun I had with One Ocean Diving on the North Shore of Oahu! Initially, I was very hesitant to book this free dive with sharks. I wasn't sure if I would enjoy facing my fears and pushing myself outside of my comfort zone. However, I am so glad I did because this was my favorite thing that I did during my time in Hawaii. If you are having any reservations about booking this experience, let me put your mind at ease. Please go. I promise you will not regret it! Our guides Tyler and Drew were friendly, professional, and prioritized our safety in the water above anything else. While I was swimming with the sharks, I never felt like I was in danger. I had an absolute blast diving into their world and observing their inherently peaceful and curious behavior. Plus, we got up close and personal with SO many tiger sharks!! I could not have asked for a more magical day. We've all been taught that sharks are mindless killers, but this could not be further from the truth. I hope to come back again, but I also know that these memories will last a lifetime. ❤️ 🦈

No words can describe this incredible experience! To be in the water, cage free, with these magnificent creatures was awe inspiring. We did the Advanced Tiger Shark program and it was worth every cent. There were some nerves at first but the team of Faith, Matt and Captain Liko were professional and warm and we immediately felt at ease. We swam with 3 Tiger sharks simultaneously and countless Galapagos sharks. There was something so peaceful about it and so moving. The icing on the cake was getting to experience all this with Ocean Ramsey herself and Juan Oliphant. What a privilege. Absolutely unforgettable!!

Doing the trip to Hawaii to go dive with One Ocean Diving was a dream for my wife & I. Turns out it was the most emotional & powerful adventure of our lives. Having the chance to learn more about them and how they protect our ocean, encountering sharks with passionate and dedicated guides who’s doing everything they can to create those unique and unforgettable moments in total respect of the marine life, there’s no words to describe the power of such an experience. If you get the chance to dive with Kaitlyn, just take it! You can feel all the respect that she has for sharks and she was so mind and attentive to us, we did 3 dives with her and a private, we can’t wait to go back again! We also got the chance to realize the biggest dream of my wife during a beach cleaning to Kahana Bay and she met the founder in person, Ocean Ramsey. We had the chance to thank her for the never-ending battle that she’s fighting everyday to protect sharks from humans, we’ll just never forget this honor we had there. Mahalo One Ocean Diving, can’t wait to come back next year for Tiger season🦈🌺🌈🌊
