Nanliao Fishing Port is located 50 m ahead of the only petrol station in Green Island. It is a flat coral reef coast that formed a slight crescent shape. It is the single, and the most important, port connecting Green Island with the outside world and the main entrance for tourists into the island. Green Island is a well-loved holiday location for Taiwanese and there are especially a lot of visitors during the summer holiday at Nanliao Fishing Port.
