After a lengthy search for just the right tour, I made reservations for Oahu Nature Tours' Ultimate Circle Tour on August 31, 2022. My husband and I thoroughly enjoyed the day. Our driver was skilled and cautious. The bus was comfortable and had large windows. Our shrimp lunch (included) was delicious.
Our Hawaiian born guide was wonderful - he shared information about Hawaii's history, culture, economy, famous residents, geography, and so much more!
Having read reviews before booking, I was aware that the women on the tour would be facing the usual long lines at the rest stops. I was also aware that due to drought conditions, the Waimea Waterfall was completely dry, but the beauty of the Waimea Valley Arboretum made that stop well worthwhile.
The only negative comment I have is that our final stop at the Dole Plantation was not for everyone. The merchandise in the store was overpriced, but at least the pineapple smell that was in the air was pleasant.
Lastly, Michael Walther's Pocket Guide to Nature on O'Ahu, which we all received, is a great source of information! I've already used it to identify birds that we saw all around the island.
