The island of Oahu, which contains the capital city of Honolulu, is a fantastic combination of urban amenities, nature hikes, and beautiful beaches. If you are doing only one island out of the four major islands Of Hawai’i, then this is the one I would recommend. I did it during Thanksgiving, which is the last week of November. While this island is not as big as the “big island”, public infrastructure outside of the city of Honolulu is not good. Therefore, I would recommend taking a moped rental(30-40$ a day) for a solo trip. Roads are narrow, and the moped turns out to be a better choice than a car, both for driving and parking. The only time a moped gave me trouble was when it rained. Outside of the city of Honolulu, there is nothing much to do after the sunset. So, plan your trip accordingly. Do check out local food items, like Shave Ice cream and Banana bread from local markets. But don’t carry any of it for the return journey.
