Saiha is located in the extreme southern part of Mizoram, nestled in the deeply forested, rolling hills of the region. The city sits near the international border with Myanmar to the east and south. The geographic landscape is defined by the larger Lushai Hills range, which extends southward from the Himalayas.
The most defining hydrological feature of the region is the Chhimtuipui River (also known as the Kaladan River), which flows robustly through the district. This river not only forms part of the international boundary with Myanmar in certain stretches but also serves as a crucial natural resource for the surrounding villages. The surrounding environment is characterized by dense, semi-evergreen sub-tropical forests, which host an incredible array of avian and terrestrial wildlife.
