Monte Rio is a small town located in Sonoma County, California, United States. The town was originally inhabited by the Pomo Native American tribe, who lived in the area for thousands of years before the arrival of European settlers.

In the mid-1800s, the area was settled by Russian fur traders and American pioneers, who established farms and ranches in the area. The town of Monte Rio was officially founded in 1901, when a group of San Francisco businessmen purchased land in the area and established a resort community.

The town quickly became a popular vacation destination for wealthy San Franciscans, who built summer homes and cottages in the area. The town’s natural beauty, mild climate, and proximity to the Russian River made it an ideal location for outdoor recreation, including swimming, boating, and fishing.

During the 1920s and 1930s, Monte Rio became known as a center for entertainment, with several nightclubs and theaters opening in the area. The town was also home to several famous musicians and performers, including Bing Crosby, who owned a home in the area and performed at the local theater.

Today, Monte Rio remains a popular vacation destination, known for its natural beauty, outdoor recreation opportunities, and historic charm. The town is home to several historic landmarks, including the Monte Rio Bridge, which was built in 1934 and is listed on the National Register of Historic Places.
