The Cold River begins at the outlet of Crescent Lake in the northeastern corner of the town of Acworth. The river flows east into the town of Lempster, then turns south and reenters Acworth. When Dodge Brook joins the river, it turns west and makes its way to the Connecticut River, passing the villages of South Acworth, Alstead, and Drewsville. The river reaches the Connecticut just south of the communities of Bellows Falls, Vermont, and North Walpole, New Hampshire.

In October 2005, flooding on the Cold River and its tributaries caused severe damage in the towns of Alstead, Acworth, and Walpole.
