Danville, CA

The Iron Horse Regional Trail runs through the middle of Danville on the corridor that created its downtown. Southern Pacific trains reached the San Ramon Valley in 1891, shifting stores, hotels, warehouses, and farm shipping toward Hartz Avenue. The railroad was abandoned in 1978, but its right-of-way now carries a regional trail between Concord and Pleasanton. In central Danville, the path passes the restored depot, the year-round Saturday farmers market at Railroad and Prospect avenues, and businesses along central Hartz Avenue. This reused line provides a simple local map: downtown sits on the former tracks, homes spread into the surrounding valley and hills, and Interstate 680 carries regional traffic along the town's western side. Agriculture preceded that rail center. Bay Miwok communities lived along valley creeks and used nearby Mount Diablo before a farming village formed in the 1850s within the former Rancho San Ramon.

Ranches and fields produced cattle, grain, fruit, and nuts; rail service allowed crops to reach distant markets throughout the year. Interstate 680 arrived in 1968 and accelerated conversion of agricultural land to housing and commercial development. Concern about controlling growth contributed to Danville's incorporation in 1982. Work now occurs mostly at a smaller scale than in surrounding office centers. A 2026 town review found that nearly nine in ten Danville businesses had nine or fewer employees, the Tri-Valley's highest concentration of microbusinesses. Downtown shops and restaurants operate alongside professional, health-care, and service offices elsewhere in town.

A literary site in the hills depends on that downtown rail history. Eugene O'Neill lived at Tao House from 1937 to 1944 and worked there on The Iceman Cometh, Hughie, Long Day's Journey Into Night, and A Moon for the Misbegotten. The house and surrounding ranch now form the Eugene O'Neill National Historic Site. Visitors cannot park at the property, so the National Park Service carries them by shuttle from the Museum of the San Ramon Valley inside the restored downtown depot. A trip to O'Neill's writing room begins beside the former tracks that once moved Danville's crops. That operational link keeps the nationally important hillside property tied directly to Hartz Avenue. Several recurring programs also fit within the old rail-centered grid.

The farmers market opens near the depot every Saturday. A few blocks away, the Village Theatre began as a farmers' lodge in 1873 and now presents plays, films, public programs, and visual-art exhibitions. Prospect Park Plaza has an outdoor stage for the At the Plaza series, while Town Green beside the library and community center hosts Music in the Park and summer movies. Danville's July 2026 calendar placed performances and screenings at both spaces on multiple weekends. The venues are small and close together, matching the business pattern along Hartz Avenue. Market stalls, theater audiences, trail users, and the National Park Service shuttle all converge around a depot that has not seen a passenger train since 1978.
