Maui is a small but beautiful island of Hawai’i. Here is a recommended 4-day itinerary for Maui. This itinerary is a slightly modified version of what I was able to do. The public transport on the island is poor. For solo travel outside the rainy season, I would recommend renting a moped to go around. Otherwise, rent a car. The island has a much more developed western part consisting of Kaanapali and Lahaina, which have major resorts.
Kauai is the nature island of Hawai’i. It is smaller than Big Island and way less developed than Oahu. Kauai is more about hikes and waterfalls than watersports.
The Island of Hawai’i, popularly known as the Big Island, is the biggest island in Hawai’i. Unlike other islands, this one is too big for driving around with mopeds. The island has two cities at the two corners, Kona and Hilo. If you are a coffee lover then you would note that Kona indeed is the source of Kona coffee.
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.
