Hala-Bala was proclaimed wildlife sanctuary in 1996. It demarcates the southernmost rain forests in peninsular of Thailand with the vast territories of 434 square kilometers covering Sangalakiri Range in Narathiwat Province, extending to the border of Malaysia. The fertile evergreen forest supports a density of huge dipterocarp trees and is home of almost all hornbill species found in Thailand. Every visit of Hala-Bala for a birder is always exciting and ends up with a new bird list.
