The place now known as Grizzly Island was named after the grizzly bears that once thrived there back in the 1800s, marking the beginning of its impressive heritage. For thousands of years, the indigenous Wintun and Patwin tribes claimed the domain as their own, before Spanish navigators arrived in the zone, founding a settlement. In the 19th century, Grizzly Island became a favoured spot for avid hunters and anglers. Farmers utilized the land primarily for asparagus cultivation during the early years of the 20th century. Subsequently, in the 1970s, the California State government procured the area and designated it as a wildlife sanctuary.
