The Hawaiian Hana Highway, known as the Road of Heaven, runs through the northeastern coast of Maui and is considered one of the most beautiful roads in the world, with vast beaches and tree-lined forests. Windy roads, black sandstones made up of volcanic gravel, lush bamboo forests and whitewater gorges... Eight hours of driving, the stop-and-go is beautiful, and if time permits, it will be enjoyable on the road one week.
