Thi Nai Lagoon

Discover Thi Nai Lagoon: A Masterpiece Lagoon Between Old Binh Dinh and New Gia Lai

Hidden behind the rocky mountains of the Phuong Mai peninsula, a vast expanse of water emerges like a giant mirror, reflecting the mystical beauty of the land and sky of the South Central Coast. This is Thi Nai Lagoon, a place that not only holds precious biological values but is also a witness to historical ups and downs. In the context of the 2026 regional planning, the connection between old Binh Dinh and new Gia Lai has made this a crucial link in the journey of discovery from the high mountains to the ocean.

From the experience of the Local Trips team, we have realized that Thi Nai's appeal lies not in the hustle and bustle of the city, but in the slow pace of life of the fishing villages along the lagoon and the tranquility of the mangrove forests. A practical lesson is that if you just pass over the sea bridge without stopping to watch the sunrise over Thi Nai Lagoon, you've missed 50% of Quy Nhon's soul. As experts at LocalTrips.ORG, we will take you on a journey through this "Hai Hac Dam" region with the most in-depth and practical perspective.

Geographical Location of Thi Nai Lagoon: The Meeting Point of River and Sea

Many tourists often wonder where Thi Nai Lagoon is located and why it is called the largest saltwater lagoon in Central Vietnam. Geographically, it is a vast saline lagoon with a water surface area of over 5,000 hectares, stretching across Quy Nhon city and the two districts of Tuy Phuoc and Phu Cat.

The lagoon is shaped like a large stomach, separated from the East Sea by the Phuong Mai peninsula – a sturdy rocky mountain range that acts as a屏風 (screen) shielding it from storms. Thi Nai plays the role of a typical estuarine ecosystem, where the Con River and Ha Thanh River converge before flowing into the saltwater at the Thi Nai estuary. With a length of over 10 km and an impressive width, this is a coastal lagoon of particular importance in regulating the climate for the coastal region.

In the current trend of regional connectivity, this area is no longer limited by the administrative boundaries of old Binh Dinh. The concept of new Gia Lai reflects close economic ties, transforming Thi Nai into the most important gateway for tourists from the red soil highlands to enjoy the cool Quy Nhon Bay.

History of Thi Nai Lagoon: From Ancient Trading Port to Naval Battlefield

The people of Xu Nau are often proud of the rich history of this lagoon. According to ancient documents, the name Thi Nai originated from the Cham word "Cri Vinaya", reflecting its deep connection with Cham Pa culture. This place was once a bustling ancient trading port, where merchant ships from the West and East Asian countries stopped to exchange goods.

In Vietnamese military history, Thi Nai Lagoon was the site of classic naval battles between the Tay Son army and Nguyen Anh's army. With its strategic lagoon terrain, this place witnessed the bravery of the people of the land of martial arts and literary tradition. In the past, the lagoon was also known as Hai Hac Dam, a name evoking the peaceful image of flocks of cranes returning to a good land. Through many ups and downs, Thi Nai Port has maintained its role as a vital trade connection point, transforming from a military port to a modern seaport.
