Further west and not far from Xinghai Park, there is the Black Reefs Scenic Spot. The coastline here twists with ups and downs. The karst landscape of black reefs, spreading over the bay, was formed about one billion years ago. The black reefs appear and disappear with the ebb and flood of the tide. Here Tourists can enjoy swimming, fishing, boating, and other activities. This area has become one of the major tourist attractions in Dalian.
