The population was 42,039 in 2010. Danville is one of the wealthiest suburbs of Oakland and San Francisco. It is home to some of the most expensive real estate and exclusive country clubs in the nation.
Every Saturday from 9:00 AM to 1:00 PM, Danville hosts a farmer’s market, where merchants gather under makeshift tents and umbrellas to sell a wide variety of goods. One can buy all sorts of fresh goods from the market, from freshly grown fruits and vegetables, to kettle corn, to baking goods, to flowers, to drinks, to olive oil, to the services of a musician who usually entertains people passing by. The market can be found on a weekly basis next to the San Ramon Valley Museum.
The Iron Horse Regional Trail runs through Danville. It was first a railroad that is now converted to a 80-foot (24 m) wide corridor of bike and hike trails as well as controlled intersections. Extending from Dublin to Concord, the trail passes through Danville. Walkers, bikers, skaters, and joggers usually find the Trail a source of outdoor recreation and exercise. Furthermore, the Trail is relatively isolated from the heavy traffic on the main roads, so it is a relatively safe path to travel on. The trail is also close to all the major bookstores, shops, cafes, and restaurants in Danville, so those who are doing a long trip often stop in Danville to eat or drink.
