Make note that the Hana Highway is renumbered to Route 360 near mile 16, even though you are still driving on the same scenic road.  As you approach new mile marker 2, look for the many cars parked by the bridge that crosses the Ho'olawanui Stream. You have reached the site of Twin Falls, the first of many magical waterfalls you will encounter on your excursion.  This area is very popular because of its location and offers hiking trails, accessible pools, and wonderful waterfalls.
