Haleakalā is Maui's defining landmark: a massive shield volcano that forms more than 75 percent of the island. The summit sits at 3,055 metres, and the crater stretching away from it is one of the most extraordinary landscapes in the Pacific — a ten-mile-wide cinder bowl of ochre, rust, and black under a sky that looks like no other.
The sunrise experience is famous and deservedly so. On a clear morning, you watch the shadow of the volcano projected across the clouds below while the Pacific horizon turns pink, then red, then gold. Arrive cold — summit temperatures can drop well below freezing even when the coast is hot. You must book a sunrise permit online in advance through recreation.gov; they are released 60 days ahead and sell out fast. The drive up is dramatic in its own right: the road climbs from sea level to the summit in about 38 kilometres, passing through every climate zone from subtropical to alpine.
The park has two districts. The Summit District has the crater overlooks, the visitor centre, and the observatories (including the Daniel K. Inouye Solar Telescope, the largest solar telescope in the world). The Kīpahulu District, reached from Hāna on the east coast, is a completely different world — lush, rainforested, and cut through by waterfalls and freshwater pools.
