Thung Sam Roi Yot Freshwater Marsh is located on the northwest corner of the National Park. It is the largest freshwater marsh in Thailand, home to many species of waterbirds, songbirds, amphibians and various wetland species. The marsh is registered as Ramsar site by the Ramsar Convention, an international treaty for recognition of important wetlands. The images of the mountains and wetlands seen in my photos, are taken in Thung Sam Roi Yot National Park.
