Hana Highway twists and turns for some forty miles, with over 600 curves and dozens of one lane bridges. Hana itself is a tiny little village of 1,200 with a couple of stores, a hotel, and that’s it. It had been a plantation town, and in many ways still is. Mostly populated by native Hawaiians, I felt in a different country, not just in a remote part of Maui. There were several “Reinstated Hawaiian Government” signs along the way too. They are part of a serious, growing movement for Hawaiian independence and should not be discounted. (See comments for more on this.)
Hana Highway passes through spectacular vistas of ocean, coves, rain forests, with each twist in the road seemingly a different eco-system. There are trailheads everywhere. Exploring all them would take months!
