The tourism and fisheries potential of Southeast Asia's largest lagoon, Tam Giang, was highlighted at a festival organised by Quang Dien District in the central province of Thua Thien-Hue on May 1 and 2, 2010.

The two-day festival was named Song Nuoc Tam Giang (Water and Waves of Tam Giang).

Locals and visitors participating in the festival had the opportunity to take tours and enjoy the natural beauty of the lagoon as well as observe daily life in the region. They could also take part in folk games, or try their hand at several traditional handicraft vocations of communities living nearby the lagoon.

Nguyen Giai, Deputy Chairman of the district people's committee and head of the festival's organizing board, said the festival sought to "awaken the potentials of lagoon tourism and attract investment to develop hotels and resorts around the lagoon."

The 52km² wide Tam Giang (three rivers) lagoon is the confluence of three major rivers – Huong (Perfume), Bo and O Lau. It is rich in terms of breakage water biodiversity and of great significance in preventing salination of agricultural land.
