The Dunnigan Hills are low-elevation hilly farmlands and winery lands that run along the western side of the I-5 corridor northwest of Woodland. I-505 passes through them. The Dunnigan Hills project from the coast range foothills (at their northwestern end) into the Sacramento Valley. Their highest peak is 456 feet.
