The island of Maui is the second most visited of the Hawaiian Islands. There are lots of great things to see and do in six days. They say "Maui no ka oi" which in English means "Maui is the best," and they may be right!
Day 1: Take a self-guided walking tour of the historic whaling town of Lahaina. You can pick up a free map to guide you to the historic sites. Be sure to visit the Lahaina Jodo Mission on the outskirts of town.
Day 2: Explore west Maui's rugged North Shore along the Kahekili Highway. End your drive in Wailuku. Visit the 'Iao Valley State Park and the Bailey House Museum. Spend the evening at the Old Lahaina Luau.
Day 3: Explore Upcountry Maui. Drive to Haleakala National Park in the morning. (Bring a jacket. It's cold.) Head along Route 37 towards Ulupalakua for lunch at the Ranch Store and Deli. Take a tour of the nearby Tedeschi Winery.
Day 4: Take a whale watching cruise (in season) or go on a snorkeling excursion at Molokini Atol from Ma'alaea Harbor. Afterward visit the nearby Maui Ocean Center in Ma'alaea. Have dinner at one of the nearby restaurants.
Day 5: Make the drive to Hana on the Hana Highway. Stop often at the many waterfalls and vistas. Continue on past Hana to O'heo Gulch and then to the grave of Charles Lindbergh at Kipahulu before returning home.
Day 6: Spend the day at Ka'anapali Beach or any of West Maui's beautiful beaches. Take time to visit the Whalers Village Museum. If golf is your passion, some of the best courses in the world are nearby.
There is so much to do on Maui that you won't be able to do it all in one trip, so don't try.
Leave early in the morning for Hana and plan for a long day. The road is very narrow with lots of curves so drive carefully.
Take some time to visit one or more of Maui's excellent beaches, generally considered the best in the world.
