Bueng Chawak is located in Doem Bang Nang Buat District, Suphan Buri Province. It is a large natural freshwater wetland formed by sediment accumulation from the Tha Chin River in the past, which eventually separated into an independent basin. Covering an area of more than 1,700 rai, the surrounding lowland terrain creates ideal conditions for one of the most fertile and diverse wetland ecosystems in central Thailand.

The wetland is rich in aquatic vegetation such as red lotus, water lilies, reeds, cattails, water hyacinths, and various freshwater algae. In the early morning, countless red lotus flowers bloom across the water surface, creating a peaceful and picturesque landscape suitable for relaxation, photography, and nature study. Designated camping areas are available for visitors, with strict regulations in place to protect the environment.

Bueng Chawak serves as an important habitat for more than 70 species of waterbirds and grassland birds, including both resident and migratory species. Commonly found birds include purple swamphens, comb ducks, open-billed storks, coots, and lesser whistling ducks. During the winter season, large flocks of migratory ducks—sometimes numbering in the tens of thousands—can be observed, making it a rare and remarkable natural phenomenon. Egrets, herons, and painted storks are also present throughout the year.

Due to the abundance of aquatic plants, Bueng Chawak is an important breeding ground for various freshwater fish species such as snakehead fish, silver barb, gourami, and other native fish. This rich biodiversity plays a vital role in maintaining ecological balance, supporting local food sources, and sustaining natural resources for surrounding communities.

In terms of conservation, Bueng Chawak was declared a wildlife non-hunting area in 1982 and later designated as a wetland of international importance under the Ramsar Convention in 1998. Today, the area is developed as a center for environmental education, research, and eco-tourism, featuring attractions such as an aquarium, a freshwater crocodile pond, a local vegetable garden, and nature study facilities. As a result, Bueng Chawak stands as a valuable natural heritage site that harmoniously combines conservation, learning, and sustainable tourism.
