Maui is a small but beautiful island of Hawai’i. Here is a recommended 4-day itinerary for Maui. This 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 which has major resorts and Lahaina which area.
Start with Road to Hanaa, it’s a day-long activity and you do want to do this early on when it’s not raining.
Don’t forget to eat Aunty Sandy’s Banana bread on the way.
Wake up early to get to Haleakala National Park to watch a beautiful sunrise. You can hike down in Haleakala National Park afterward. Its interesting flora and fauna but not a great hike.
In the evening, head to Kaanapali, the beaches are great and do jump off the Black Rock cliff into the Pacific ocean.
Head south to Makena State Park, Big beach is another beautiful beach there. Do note that it is very similar to Black Rock beach, so, you can skip this entirely. In the evening, head to Lahaina to check the largest Banyan tree in the United States.
Head to Iao Valley State Park for hiking. Spend rest of the day checking Wailuku and local delicacies.
