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.
