Glenn County, California
Glenn County is located in California’s northern Sacramento Valley, where agriculture dominates the landscape. The Sacramento River forms much of the eastern boundary, while the Coast Ranges rise to the west, creating a scenic backdrop for this quiet rural region.
Willows serves as the county seat and largest community, known for its relaxed, small-town atmosphere. Interstate 5 runs through the county, providing an important transportation link while leaving much of the surrounding area relatively rural.
Birdwatching is another popular activity, especially at the Sacramento National Wildlife Refuge in the southern part of the county. The refuge provides important habitat for millions of migrating geese, ducks, and other waterfowl each year. With its farmland, river landscapes, and nearby mountains, Glenn County offers a peaceful slice of Northern California.
