Lassen County, California

Lassen is up in the northeast corner of California with a population that hovers around 33,000 people. It’s where high desert meets forest, with Lassen Volcanic National Park as the star attraction.
Susanville is the main town, but it’s pretty small. The county has more cows than people, no joke. There’s also great hunting and fishing if that’s your thing.
Highway 395 runs through the county, linking it to Reno, Nevada, just an hour’s drive away. Lassen County is the kind of place where everyone waves when they drive by, even if they don’t know you.
