The Nanwan Wharf Recreation Area (南灣碼頭遊憩區), sitting at the southern extremity of the Cigu Lagoon (七股潟湖), is a great place from which to enjoy the mangrove forest landscape and gaze out towards nets, wooden shacks, and bamboo fish traps. The dock features a viewing platform, and is also a place from which to catch pleasure boat trips into the lagoons. You can take a boat to Wangzailiao Barrier Island or Dingtouershan Sand Bank, and you will find yourself surrounded by diverse ecology ranging from fiddler crabs to water birds, and mangrove forests. The lagoon itself is truly a wonderful site, with beautiful lagoons, oyster sheds and sand banks. As the lagoon is only knee-deep, you can get off the boat and search for shellfish on the beaches and enjoy the fiddler craps; and a trip to enjoy the ecology of Cigu Lagoon takes approximately two hours.
