The district is in the upper valley of the Ing River. West of the town Mae Chai is the 1,426 m high Doi Luang mountain of the Phi Pan Nam Range. It rises within a protected area in the Doi Luang National Park. To the east is the Nong Liang Sai Reservoir, and at the boundary to the Mueang District the Mae Pim Reservoir.
