Great local tour guides. Worth the money to include this in your vacation.
We have gone on this tour twice - once in 2025 and once in 2026. Both times with had very knowledgeable local guides. They were able to give lots of history and personal insights to Kauai. Both were great drivers and went out of their way to make the day enjoyable. Both years we had to switch the day of our tour due to rescheduling of other activities. The company was very easy to work with to make the changes. Very worth the money to have this experience on Kauai.

Amazing Na Pali Coast Adventure with an Incredible Crew! 🌊⭐️
The overall tour of the Na Pali Coast was absolutely amazing! 🌊 The boat tour was a fantastic experience, with breathtaking views, beautiful scenery, and an unforgettable adventure on the water. The snorkeling was also a highlight, with beautiful clear water and an amazing opportunity to be in the ocean. The crew was so much fun, friendly, and full of great energy. They made us feel welcome, and really went above and beyond to make the experience memorable. Their enthusiasm and knowledge made the trip even more enjoyable. I highly recommend this boat tour to anyone visiting Kauai—it’s definitely an experience you won’t want to miss! Thank you Josh, Aaron, Keala, and Andy for making this tour memorable and amazing ⭐️⭐️⭐️⭐️⭐️
