"After reading lots of reviews here on tripadvisor about these guys I booked an 8 hour tour for January 2017 for our group of 8 ranging in age from 10 to 53. Greg arrived right on time in a perfectly clean and spacious van and took us to Diamond Head lookout where he pulled out his map of the island for us to discuss and plan our day. As we were on Oahu for only a couple of days we wanted to see as much of the island as was possible without Pearl Harbour or Diamond Head which we knew we could do on other days. Greg gave us 2 options- a route that would take 8 hours or we could extend it to 10 hours to fit in the south east corner which we were interested in. 10 hours sounded like it would be way too long to me but majority ruled and I'm glad it did. We had a fabulous day and learnt so much along the way. I don't recall there being any questions that Greg wasn't able to answer and believe me, we are an inquisitive bunch. I highly recommend this company to anyone wanting to not just see Oahu, but to learn a lot about the history and culture as well. Pali lookout, Waimea Bay and the huli huli chicken we had for lunch were standouts for me."
