Even when compared to the other Hawaiian islands, Maui stands out as unique. Thus the term “Maui No Ka Oi” (which means Maui is the best) has become a common and well known local term used to describe the island.One of the most amazing areas of Maui is the road to Hana. Whether you drive yourself or enjoy a relaxing Hana tour there is something special in the Hana rainforest that you should stop and see… the Rainbow Eucalyptus tree.Around mile marker 7, you can catch a grove of rainbow eucalyptus trees. The natural multi-colored bark of the trees is caused by patches of outer bark that are shed annually at different times, revealing a bright green bark underneath. The bark matures and darkens into streaks of red, blue, green, orange, and purple that constantly change as the tree continues to grow.
