More ways to explore the area's outdoor wonders
You step off the minibus onto sun-warmed coral rock and the wind from the Pacific pulls at your shirt, carrying salt and a ringing gull cry. The road here threads past low coconut palms and small villages; soon the Ha'amonga 'o Maui trilithon rises ahead — three upright stones that frame the horizon like an ancient doorway.
