I’m a good swimmer so I didn’t panic, however, I was curious as to how I was going to get back into the kayak. Long story short, Faith talked me through everything, she’s very knowledgeable and extremely fun to be around. I recommend you kayak with her.”

“Danielle and David took us to where Finding Nemo and Moana got their inspiration and we can see why. The water was so calm and pristine, our best camera couldn't capture the beauty of it. You just have to be there truly. They were rather knowledgeable and told lots of stories and history tidbits about the region. My parents came to visit from China and don't swim very well. They were beyond patient and kind making us feel comfortable. This was the highlight of our 10 day Hawaiian trip honestly. PS: If David's mother is reading this, David is a terrific captain and really great at his job!!! 🌴”
