This was an amazing tour! My wife and I were in Kauai to celebrate our 35th wedding anniversary, along with one of our sons and his girlfriend. We had so much fun on this trip! The captain and crew were outstanding. The captain pointed out many things of interest and was very knowledgeable. His crew mates were so friendly, polite, and ready to help with anything that you needed. We had a lot of fun snorkeling, and getting to see the Na Pali coast was absolutely incredible! If you are prone to motion sickness, do take some Dramamine or something to help with that, because you do bounce around quite a bit, especially on the way back, as the tradewinds start to pick up in the afternoon typically. You will also probably get a little bit wet, besides when you get in the water to snorkel, from some of the waves splashing up into the boat. But to all of us in my party, it just added to the fun of the whole experience.
I can honestly highly recommend this tour!
