The sky is not beautiful, sometimes dark clouds, sometimes light rain, sometimes see rainbows, the fjord ten miles different days. As the ferry propelled, the mystery of the bay gradually emerged. Gaiwan is 15 kilometers long, and the two sides stand more than 1,500 meters of cliffs. Many large and small waterfalls are falling down. The most famous are the "groom veil" and "seven sisters". At the top of the fjord is Gailang Earl Village, which has become a tourist distribution center. The village can be extended from Gai to other attractions, and Gaiwan was included in the United Nations World Heritage Site in 2005.
