Halawa Valley Scenic Road (SR 450) begins with soaring tropical slopes and vast, sapphire seascapes. Water occasionally splashing across the narrow road heightens the drama. The byway turns from the coast and ascends sea cliffs into a tropical forest, then steeply descends into lush Halawa Valley. Pullouts offer spectacular views of cliffs, islands and waterfalls.
