Despite the small size of this island, it can take a couple of hours to travel between the popular destinations. Many sights are isolated and difficult to find; you may be better off taking an organized excursion. If you do go it alone, drive carefully; roads can be narrow, winding, and unmarked. Plan at least eight hours to see the highlights. To fully experience the island, set aside about five days so you can enjoy the water and take some hikes.
