I decided to book this tour without much research. We had an extra day on Oahu and decided to take a general tour to be sure to see all of the highlights. This did not disappoint.
Our tour was led by Ian (aka, “Trevor” - once you meet him you’ll understand ...) and Dennis was our driver. They were a great team. Ian is quite a character. Personable. Entertaining. Extremely knowledgeable. Ian managed to convey a deep respect for the Islands and the culture of Hawaii while simultaneously being totally irreverent and funny. Dennis was a great partner. He was more reserved than Ian. But, Robin WIlliams was probably more reserved than Ian ...
The tour checked all of the boxes if you want to see the highlights. The tour is not intended to go in depth at any particular location. For example, you go to Diamond Head, but you don’t hike it. But, that’s the entire point - to see it all in one day. Mission accomplished. The highlight was probably the snorkeling - the tour guides are licensed life guards and ensured that everyone had a great time while being safe.
I’d suggest doing this trip on your first day on the Island so that you can get a lay of the land and then determine which sites deserve a closer look. A+
