The Duck Mountain Provincial Forest is located on the Saskatchewan / Manitoba border. The forest sits atop the Duck Mountains, which rise 200-500m above the surrounding prairie, and are part of the larger Manitoba Escarpment. The forest is designated as a provincial forest on both sides of the border. The Manitoba portion of the forest has an area of 3,770 km² (1,455 sq mi), which includes all of the park's area of 1,424 km² (550 sq mi). The forest was established in 1906. It is the largest Provincial Forest in Manitoba, slightly larger than the next largest Swan-Pelican Provincial Forest.
