Anin is located eastward when viewed from Chilsadang, the administrative office of Gangneung city during the Joseon Dynasty. The name “Anin” combines “An,” meaning comfort, and “In,” indicating the east direction, signifying a peaceful place to the east of Gangneung. Around 85 households in Anin are engaged in fishing, with approximately 42 fishing vessels. The main catch includes flounder and halibut, along with abalone and various seaweeds. Notably, halibut and abalone are actively farmed. The primary coastal fishing grounds lie within 1–5 km offshore. The main fishing season runs from October to February, primarily harvesting flounder and halibut. Where the Gunsun River meets the sea, mullets are abundant, attracting local fishing enthusiasts. Every year, a rich harvest festival is held on March 3 and September 9.

A little further down from Anin Port, you will reach Jeongdongjin. Here, visitors can purchase fresh seafood and enjoy nearby golf courses, offering a scenic view of the expansive sea while playing. There are also horseback riding centers and natural recreational forests nearby, providing memorable experiences for families with children.
