Danville is an unincorporated community in Contra Costa County, governed by the county with a population of approximately 45,000. Its setting at the foot of Mount Diablo provides dramatic scenery and abundant recreational opportunities. The town's history as a 19th-century farming community is preserved in its charming downtown, where restored buildings house boutique shops, restaurants, and services along Hartz Avenue. Danville experienced significant growth in the late 20th century as families sought excellent schools and quality of life, resulting in well-planned neighborhoods with varying home styles—from modest single-family residences to gated luxury communities like Blackhawk. The San Ramon Valley Unified School District serves Danville, with schools consistently ranking among California's best. Mount Diablo State Park, which rises dramatically from the valley floor, provides a spectacular natural backdrop and access to hiking, cycling, and scenic drives to the summit.
