Glenn County is a quiet Sacramento Valley gem where you and your dog can enjoy wide-open farmland, wildlife areas, and small-town charm. The Sacramento National Wildlife Refuge complex is one of the premier birding destinations in California, and leashed dogs are welcome on levee roads and walking paths around the refuge.

The county seat of Willows offers a relaxed stopover with local parks and outdoor dining. Nearby, Black Butte Lake provides hiking trails, shoreline walks, and picnic areas where leashed pups can stretch their legs and cool off. For more remote exploring, head west into the foothills along Mendocino National Forest roads, where you will find uncrowded trails and seasonal creek crossings ideal for adventurous dogs. Glenn County may be small, but its natural beauty and peaceful pace make it a rewarding detour.
