Haleakala is a massive dormant volcano that comprises about 75% of Maui. Its peak is 10,023 feet (3,055 m), so reaching it requires an epic, two hour ride from the beach up its long, windy slopes. You won’t notice the drastic change in altitude until you glance out a side window and realize that the town you left has become nothing but a speck. Along the way, you’ll drive through peaceful fields, parks, and forests, eventually reaching a point where there’s nothing but sparse vegetation, endangered species, and lots of rock. The lovely green countryside in this photo looks nothing like the summit.
