If you want an even slower tour of the island, then walking is your best choice. This is the best way to see the island and talk with some of the locals. You can walk into a school or government center and ask questions. Tahitians are kind and inviting. This way you can see their way of life and really get to know the island. After all, humans make up 75% of the beauty that the island offers so DON'T MISS IT!
Another great reason to walk or hike: It's free (with the exception of a few fat cells)! So get out and mingle when you get there.
