Guerneville (pron.: // GƏRNĒ-vil) is an unincorporated town and census-designated place in the Russian River Valley of Sonoma County, California, United States. The town is known for its historical LGBT community and culture, making it a popular destination for both homosexual and heterosexual couples, and for corporate retreats and family and friend reunions. Guerneville is also known for its natural beauty, liberal atmosphere, and proximity to wine-tasting and redwood forests. It was founded by the Guerne family in the 1850s.
Guerneville is built adjacent to the Russian River. Redwoods grew in the riverbed with such vigor that just a few centuries ago, the valley had the greatest biomass density on the planet, according to local lore. The local Pomo Indians used the area as a summer camp and called it "Ceola" (// or cee-oh-lay) which meant "shady place." Except for a large, beautiful stand of truly ancient trees preserved in the Fife Creek watershed, now the centerpiece of Armstrong Woods Park, many of the trees were logged in the 19th century, giving rise to the first English name for the place – "Stumptown." The annual town parade still commemorates the old place name by calling itself "Stumptown Days." The present name Guerneville was introduced to honor Swiss immigrant George Guerne, a local businessman of the 19th century who owned the town's sawmill. The extensive redwood forests on the surrounding mountains are less than 200 years old, having been replacement plantings for much of the logging done in the 19th century.
The area became popular with wealthy vacationers from San Francisco in the late 19th century. The San Francisco and North Pacific Railroad linked the town to the Ferries of San Francisco Bay in 1877. Even with the demise of train service in the late 1930s, the area's resorts remained popular with vacationers who came by automobile through the 1950s. A local movie theater, the River, was built near the beach and showed double features throughout the 1950s and 1960s. The coming of jet airplane travel in the 1960s marked a period of decline for many of the older resorts. Winter floods in 1964 caused a further decline in business conditions. Many housing units that were once summer-only cottages began to be used year-round by low-income households, and illegal drug use became more prevalent throughout the region. However, a renaissance took place in the late 1970s as large numbers of gay men and lesbians from San Francisco identified the area as a prime recreational destination for weekends. Many older resorts gained a new lease on life with the new visitors, and in general, the town's businesses began to thrive again.
HIV ended Guerneville's reputation as a primarily gay destination as more families and retirees moved into the area and resorts, once gay, turned to a straight or mixed clientele. Guerneville has continued to thrive with a very eclectic population and is one of the most gay/straight integrated communities in the country. There are still a few gay resorts, but the largest once gay resort is now very much a straight wedding destination, and by far the bulk of the tourist lodging lies in vacation rentals, welcoming all clienteles.
Modern Guerneville continues to exude small-town charm, from its plaza in the town center with permanent chess tables, to small shops, and a public beach area in the heart of town along the Russian River that is used for fishing, swimming, boating, and sunbathing. Just as in the past, the river is open to the public.
LGBT community 
The town is a vacation destination for people throughout the San Francisco Bay Area and beyond. It hosts an annual Lazy Bear Weekend in late July or early August, Polar Bear Weekend, in mid-January (gay bear charity events for the LGBT community), and Women's Weekend in the summer.
Guerneville is also home to the Russian River Sisters of Perpetual Indulgence, a chapter of the Sisters of Perpetual Indulgence, which holds entertaining events in various venues along the Russian River, including monthly bingo games.
There are several LGBT-friendly clubs and bars in Guerneville, such as Rainbow Cattle Company. Seth Montfort, composer and classical pianist, performs both solo and with "The Mortuary Orchestra of Guerneville" (formerly San Francisco Concerto Orchestra) at the "Music Inside Out & Center."
Local politics 
Guerneville is politically progressive, consistent with most of western Sonoma County politics.
Redevelopment in the town of Guerneville has been a controversial issue. Likewise, in the neighboring town of Monte Rio a waste-water sewer project is opposed by many, and there is a belief among some people that the two projects are inter-related and that both could possibly harm the environment.
In the media 
Guerneville's older metal truss bridge can be filmed from the newer bridge, and made an appearance in the movie Mumford as a location for people to walk and talk in idyllic settings. The independent film Deep Dark Canyon was filmed in Guerneville. Surrounding communities were also regular filming locations for the 1960s television series Combat!.
Guerneville is the home of radio station KGGV-FM, 95.1 The Bridge, (www.kggvfm.org) a 24/7 non-profit, commercial-free, community-interactive radio station which features a wide variety of locally-produced programming, streaming live on the web.
The Russian River area occasionally appears in local and/or national news due to significant winter flooding, the worst of which occurred in 1986. Long-term residents treat floods as a very occasional headache, but a reasonable price paid for living in a beautiful place. Because much of the housing is elevated, thanks in large part to FEMA grants, floods no longer have the impact they once did and recovery for most residents and businesses is much faster than in earlier times. The effects of floods are mitigated by the extensive upstream floodplain storage capacity of the Laguna de Santa Rosa.
The CDP has a total area of 9.88 sq mi (25.6 km2). Of that, 9.71 sq mi (25.1 km2) is land and 0.17 sq mi (0.4 km2) (1.72%) is water.
Guerneville has cool, wet winters and warm, dry summers, a climate typical of northern coastal California. Although rainfall is rare during the summer months, fog often comes up the river from the Pacific Ocean, producing enough condensation to create "fog drip", which sustains the numerous redwood trees, ferns, and other vegetation.
The National Weather Service reports that Guerneville has an average annual rainfall of 49.15 inches (1,248 mm). Measurable precipitation occurs on an average of 73 days each year. The wettest year was 1970 with 70.20 inches (1,783 mm) and the driest year was 1949 with 31.34 inches (796 mm). The most rainfall in one month was 29.08 in January 1970. The most rainfall in 24 hours was 8.40 inches (213 mm) on February 8, 1960.
