According to the United States Census Bureau, the city has a total area of 12.5 km² (4.8 mi²). 12.2 km² (4.7 mi²) of it is land and 0.3 km² (0.1 mi²) of it (2.28%) is water.
Mill Valley is located on the western and northern shores of Richardson Bay, fed by Pickleweed Inlet and Arroyo Corte Madera del Presidio which traverse through Mill Valley. Beyond the flat coastal area, it occupies narrow wooded canyons, mostly of second-growth redwoods, on the eastern slopes of Mount Tamalpais.
At least 500 years ago, the region that now encompasses the town of Mill Valley was inhabited by the Coast Miwoks. In 1579, Sir Francis Drake is reported to have anchored at Drake's Bay, just north of what is currently Mill Valley. However, he did not land for any specific purpose other than to make minor repairs on his vessels. His stay was limited to five weeks, during which he traded items with the Miwoks which have since been recovered in local excavation sites.
Nearly two decades later, in 1595, the Portuguese captain Sebastian Cermenho landed at Drake's Bay while piloting a treasure galleon from Manila to Mexico. He, too, came in contact with the indigenous inhabitants during his brief stop there. No further European contact was made with the Miwoks until 1775. On August 5, 1775, Juan Manuel de Ayala sailed into San Francisco Bay. It only took one year before the Spanish had erected the Fort Presidio and the Mission Dolores, both of which still exist today. In the following years, many of the Miwoks were relocated to labor in the Mission Dolores, and later in the San Rafael mission. Unaccustomed to these living conditions, many Miwoks died working in the missions. Epidemics of consumption, syphilis, measles, and smallpox--introduced by Spanish settlers in the 1820s and 1830s--also contributed to the skyrocketing mortality rate of the local peoples. By 1840, 90 percent of the region's Miwok population had been indirectly eradicated. Marin, the name of the county in which Mill Valley now resides, was named after a Miwok "outlaw" whom the Spanish had dubbed Chief Marin, because of his abilities on the water ("marinero"). He was later converted, baptized, and buried at the San Rafael Mission.
In 1834, the Mexican government gained control of the area. Miwok ancestral lands were divided and doled out to willing pioneer ranchers. The huge tracts of land, called "ranchos" by the Mexican settlers, soon covered the area. The Miwoks that had not died or fled were employed on these ranches. John Reed, mentioned above, was one of the first of these new settlers, and it was Reed's saw mill that provided the lumber and employment that served as Mill Valley's first impetus for growth. Soon after, with the Gold Rush of 1848, Mill Valley saw unprecedented growth. Shrewd entrepreneurs such as Samuel Throckmorton (for whom Mill Valley's most prominent street is named) began purchasing and selling land to the droves of prospectors that arrived from abroad.
Mill Valley's growth, and the simultaneous growth of its neighboring towns, ousted the native Miwok population once and for all. In 1852, a census counted 218 full-blooded Miwoks remaining. By 1888, there were only six. Today, there are none who claim even fifty-percent ancestral heritage among the Miwok.
The city is named for a saw mill established by John Reed in the 19th century, the site of which is now Old Mill Park. When the wooded area had been completely logged over, it was divided into small and irregular building lots, which were sold at auction. Many of the vacation homes built at that time were converted to residences during the Great Depression of the 1930s, especially after the Golden Gate Bridge eased access to San Francisco. It is now an affluent residential suburb, much of which is reached by narrow, winding roads created in the early 20th century that often incorporated the old logging roads carved out in the previous century.
From 1896 to 1930, the Mt. Tamalpais and Muir Woods Railroad ran service from Mill Valley to the summit of Mt Tamalpais. The long line had 22 trestles and 281 curves earning it the nickname "The Crookedest Railroad in the World".
Mill Valley has a mild Mediterranean climate. Daytime highs range from about 52 to in the winter, and about 60 to 74 degrees during the rest of the year. Nighttime temperatures in winter rarely drop below 38 degrees. There is abundant rainfall (sometimes per month) in the winter, and some rain in early spring and late fall. Summer temperatures vary much more than those of the winter. Much of the time, there is abundant sunshine with temperatures between 75 and 90 degrees, and humidity between 20 and 40 percent. Fog from the coast can bring cool summer weather, with midday temperatures often not exceeding 65 degrees. Nighttime summer temperatures seldom drop below 60 degrees. Summer evenings can be breezy, with warm east winds, and it is not uncommon for there to be no rainfall between mid-June and mid-October; however, dew can often be found on plants in the early morning. Because of Northern California's mild summers, few residents have air-conditioning in their homes. May through October is considered "fire season," because most water-reliant grasses die when rain ceases in May. The grasses become dry and extremely flammable, and local fire agencies prohibit most kinds of outdoor burning, fireworks, and barbecues.

is in June, although the trail can be run or hiked any time. The West Marin Stagecoach is a bus that runs from Stinson Beach back to Mill Valley, stopping approximately one mile from downtown..
The Dipsea Trail is not well marked, so first timers should consider carrying a guidebook.The combination of Mill Valley's idyllic location nestled beneath Mount Tamalpais coupled with its ease of access to nearby San Francisco has made it a popular home for many high-income commuters. Over the last 20 years, following a trend that is endemic throughout the Bay Area, home prices have climbed in Mill Valley (the median price for a single-family home is in excess of $1.5 million as of 2005), which has had the effect of pushing out some earlier residents who can no longer afford to live in the area.
In July 2005, CNN/Money and Money magazine ranked Mill Valley tenth on its list of the 100 Best Places to Live in the United States. In 2007, MSN and Forbes magazine ranked Mill Valley seventy-third on its "Most expensive zip codes in America" list.
While Mill Valley has retained elements of its earlier artistic culture through galleries, festivals, and performances, its stock of affordable housing has diminished, forcing some residents to leave the area. This trend has also affected some of the city's well-known cultural centers like Village Music and the Sweetwater Saloon. As of April 2007, only one affordable housing project was underway: an initiative to raze and rebuild an abandoned motel called the Fireside.
Mill Valley is known for being an "artsy" little town. Driving or walking downtown Mill Valley will discover many art galleries, coffee shops, and other hallmarks of a typical art town.

In addition, Mill Valley's Chamber of Commerce has sponsored the annual Gourmet Food and Wine Tasting in Lytton Square for many years.
Theater arts also have a huge following in Mill Valley. In addition to supporting the local 142 Throckmorton Theatre, which hosts theater of all levels, Mill Valley is also home for the Marin Theatre Company, as well as the Mountain Play Association which hosts annual musical productions in the Cushing Memorial Amphitheater located in Mill Valley's neighboring Mount Tamalpais State Park. For several years the Curtain Theatre Group has also been performing annual free Shakespeare plays among the redwoods on the Old Mill Park Amphitheatre behind the Mill Valley Library.
In fiction, character B.J. Hunnicutt from the TV show M*A*S*H called Mill Valley home, and fictional character Charley Furuseth in Jack London's 1904 novel The Sea-Wolf, apparently had a summer cottage here. In the Star Trek universe, it is home to the 602 Club. It is also the setting for resident author Jack Finney's 1954 novel The Body Snatchers, although the 1956 film, Invasion of the Body Snatchers, and subsequent movie versions of the book have been set elsewhere. Fictional character Doris Martin from the TV show The Doris Day Show (1968-1973 TV series) called Mill Valley home as well.
Cyra McFadden (born c. 1939) is an American writer, living in the San Francisco Bay Area. McFadden's 1977 novel The Serial: A Year in the Life of Marin County satirized the trendy lifestyles of the affluent residents of Marin County, California, just north of San Francisco. The highly successful book was made into a 1980 movie called Serial (1980 film), starring Tuesday Weld and Martin Mull. The song "Mill Valley", recorded in 1970 and released on the album "Miss Abrams and the Strawberry Point 4th Grade Class, became a nationwide hit. (Listen to a clip of |"Mill Valley")

The most recent event that attracted national attention to the city of Mill Valley was the case of John Walker Lindh, who lived in neighboring San Anselmo, and converted to Islam at the Mill Valley Islamic Center. Following his trial, former President George H. W. Bush is reported to have called Lindh a "misguided Marin county hot-tubber", which amused most Marin residents and angered some.
On January 31st, 2008, Mill Valley's sewage treatment plant spilled 2.45 million gallons of sewage into San Francisco Bay. This marked the second such spill in Mill Valley within a week (the previous one spilled 2.7 million gallons), and the most recent of several that occurred in Marin County in early 2008.
Mill Valley's treatment plant attributed the spills to "human error". Two investigations are still attempting to uncover why over 5 million gallons of sewage, most of which was raw and untreated, is now in Mill Valley's watershed. The investigations are being carried out by the Regional Water Board and the EPA. The spills caused distress in Mill Valley's administrative government, which remains outspoken about "dedicating itself to the protection of air quality, waste reduction, water and energy conservation, and the protection of wildlife and habitat" in Mill Valley.
