The route most often taken is to head toward the dark green island and take a left traveling up the little river. Once you reach the top of the island, take a right and float back down the length of the island, in the main part of Savannah River. At the bottom of the island you will notice that it cuts back up to the right taking you back to the entrance to Bettys Branch, where Oa Riverside Rentals is located.  The island is called Germany Island, a privately owned island that is home to tons of wild life as well as a few holes for the golf course Champions Retreat.
