Red Bluff is the county seat and largest city of Tehama County, California, located in the northern part of the state along the upper Sacramento River. With a population of about 14,700, it anchors a micropolitan region that serves as a commercial and governmental hub for the surrounding ranching and agricultural country. The city is bisected by Interstate 5, which runs directly through the area and connects it to the rest of the state. Red Bluff's origins date to the 1840s, when the area was settled near what was then the head of navigation on the Sacramento River. Early hamlets with names such as Leodocia grew up around this river landing, and the settlement that became Red Bluff took shape in the early 1850s. Its position on the river made it a key shipping and trading point during the Gold Rush era and the decades that followed. The city has served as the Tehama County seat since 1857. Today Red Bluff functions as a practical regional center with a distinctly Northern California character. Its historic downtown offers local shops, eateries, and antique stores, and the community is known for its longstanding rodeo tradition and the Tehama District Fairgrounds. The city sits along the Sacramento River, with a public recreation area that provides boating access and riverfront recreation. The surrounding landscape is defined by oak-studded hills, ranchland, and the volcanic terrain of the southern Cascades. Red Bluff is frequently described as a gateway to Lassen Volcanic National Park and to the outdoor recreation of the northern Sacramento Valley, giving residents a combination of small-city convenience and ready access to open country.
