This tour was outstanding, as was our tour guide, Melissa. We 2 people were the only ones on this tour and, as promised, we were able to pick which sites to see and how long to stay at each. We never felt pressured. One note: the Viator description includes Nuuanu Pli lookout as an option it isn't. This is a circle tour meaning it circles the island, and that lookout is in the center of the island. But there were plenty of other things to see all of them quite spectacular.
We travelled in a beautifully presented Mercedes People carrier driven by Ana. He was a very informative guide showing us all the beauty points around the island. The whole experience was better than we expected and very good value. If you are considering going to Ohau contact Ana at V808-387-1899. Enjoy a beautiful place.
