Thung Yang Si National Reserved Forest is a protected forest area in northern Thailand, offering rich biodiversity, scenic mountainous landscapes, and opportunities for nature exploration and wildlife observation.
Thung Yang Si National Reserved Forest is located in the mountainous region of Chiang Mai Province in northern Thailand. This forest reserve spans a diverse range of elevations, supporting mixed evergreen and deciduous forest types, including patches of teak and pine trees. The area provides habitat for a variety of wildlife species, including several bird species, small mammals, and endemic plants. The terrain offers rugged hills and valleys, making it appealing to adventurous hikers and naturalists. Although it is officially designated as a National Reserved Forest, meaning its primary purpose is conservation and controlled use, it is open to visitors seeking tranquil natural experiences away from urban centers. The forest has a history rooted in sustainable forest management practices implemented by the Royal Forest Department of Thailand. Ecotourism activities such as birdwatching, trekking, and nature photography are popular here. Visitors can explore trails that offer views of forest canopies and serene streams, while also learning about local conservation efforts. The area serves as an important watershed and plays a critical role in protecting soil and water resources. Although less developed for tourism compared to National Parks in Thailand, Thung Yang Si provides an authentic forest environment with limited infrastructure but strong ecological value. Its proximity to Chiang Mai city makes it accessible for day trips or overnight outdoor trips with proper permits.
