The dramatic landscape is characterized by the highway’s cliff-hugging road, blind hairpin turns, huge rock walls and Haleakala’s massive mountain ridges. The highway is less crowded than the Hana Highway, populated by dedicated travelers, local farmers and a United States Postal Service mail Priusthat’s right, the USPS delivers the mail in a hybrid electric vehicle!
