Tourists often equate Hawaii with relaxation, but one of its most well-known attractions—the Road to Hana—might have you gripping a steering wheel tightly. Stretching for 103 kilometres along the northern coast of Maui from Kahului to the quiet town of Hana, the highway has over 600 curves and numerous one-lane bridges. The drive takes focus, so don"t forget to stop and relax at the lush rainforests and cascading waterfalls. Some highlights along the route include the Waikamoi Ridge Trail, the easily accessible Twin Falls and the black sands of Waianapanapa State Park.
