Marlon made the tour honestly. Super knowledgeable, fun, and easy to talk to. He kept everything interesting and made sure everyone felt included. The tour was good, but he’s what made it great. Definitely recommend, especially if you get him.

Reviews: Oahu: Circle Island Top Sights Full-Day Tour w/ Local Guide
Guest User2026-10-04
I had a wonderful time on the Circle Island tour! Our guide, Chelsea, was absolutely lovely—patient, helpful, and very humorous. Because we were circling the whole island, some of the travel between the different sights can be quite long. However, Chelsea is such a great storyteller that she kept us fully entertained the entire way. She shared so much fascinating Hawaiian history and local stories, which made the transit time fly by. I really learned a lot from her by the end of the trip! If you want to see the top sights on O'ahu while actually learning about the culture and history, this tour is a great choice.
