Julian is a census-designated place (CDP) in San Diego County, California, which developed as a classic gold rush boomtown in the 1870s after gold was discovered by Fred Coleman, attracting miners, a tent city, rapid growth with saloons and stores, and discussions of becoming a county seat, before transitioning into a more stable community with agriculture and tourism. As of the 2020 census, the population was 1,768, up from 1,502 at the time of the 2010 census.
Julian is an official California Historical Landmark (No. 412). The Julian townsite and surrounding area is defined by the San Diego County Zoning Ordinance Section 5749 as the Julian Historic District. This designation requires that development adhere to certain guidelines administered by the Architectural Review Board of the Julian Historic District, which is appointed by the San Diego County Board of Supervisors.
Julian was named an International Dark Sky Community by the International Dark-Sky Association in May 2021. It was the 30th such designation and the second in California.
The town is known for its apple pie and its annual Julian Apple Days Festival, which began in 1949.
History
19th century: Initial European settlement and the gold rush
The first European settlers were "Cockney Bill" Williams from England and John Wesley Horrell, who arrived in the area in 1850 or 1851. The town was first settled by Drury, Frank, and J.O. Bailey, all brothers; and their cousins, Mike and Webb Julian. They passed through the region in 1869 from San Bernardino en route to Arizona, in the wake of the American Civil War. Taken by the beauty of the Julian area, Drury Bailey interrupted the group’s travel plans and chose to settle there; he named the settlement “Julian” after Mike Julian because “Mike was better looking” than any other member of the Bailey family. who was later elected San Diego County Assessor. Shortly afterwards gold was discovered in the Julian region. A tent city initially formed in the boomtown era, followed by more permanent structures as it became apparent that gold mining in Julian would persist for some time. Victorian-style structures were constructed in the latest stage of Julian's early settlement, including the Hoskins House. Local historians have variably suggested that the Julian of 1873 rivaled San Diego in population and they unsuccessfully attempted to shift the county seat to the city. Of the 55 Black people living in San Diego County during the 1880 census, 33 lived in the Julian area.
20th century
In 1976, Julian approved a plan that required the exteriors of any buildings on Main Street be no younger in age than 1913. Many structures bear a Victorian architecture that predates this cutoff. In the 1970s, as many of 25,000 visitors visited the settlement per annum.
On May 29, 1989, Benjamin Haimes of Encino and Gustav Oran Hudson of El Cajon) disputed a claim to land to the Ready Relief and Hubbard Mines in Julian’s Chariot Canyon (historically owned by the Bureau of Land Management) over rights to an area where both had intentions to prospect for gold. Hudson and his family arrived at the property at a time when Haimes’ appointed caretaker (Chris Zerbe) and the caretaker’s friend (Joe Lopes) of Julian. The resulting escalation involved the replacement of a padlock at the Hubbard Mine by the Hudsons, conflicting accounts of alcohol use and escalative behavior by Zerbe, and a shootout in which Zerbe and Lopes (who did not fire) were ultimately killed. No charges were filed. Nicknamed the “Chariot Canyon Massacre,” these killings are understood to be the first gold prospecting-related killing in Julian since the gold rush of the late 1800s.
A controversy erupted in Julian in 1991 as the community lost its bid to resist the construction of fast food restaurants. Dairy Queen and Subway were the first to relocate to the town during this time. Zweig circumvented a community moratorium on new development (induced due to the town’s longstanding drought), agreeing to continue selling 30,000 gallons of water a day in return for the waiver to build. Zweig, also the owner of the largest well in the community, allegedly threatened to cut off the community’s water supply unless they acquiesced. The Marie E. first ran in 1968. Johnston sold the vacation estate and the narrow gauge train in 1993,
21st century
The region around Julian was hit by a multi-year drought starting in 1999, leading up and into the catastrophic Cedar Fire of 2003 following an extremely wet 1997–1998 El Niño cycle. Residents of Julian reported drilling wells up to to strike water during this period, well over twice as deep as they have had to drill in the town’s history. This has also been controversially attributed to stressors from the development of weekend and holiday housing in the town by outsiders. Drought conditions were noted to have allowed the rise of beetle pests to consume Coulter pines in and around the community, as the pines do not have access to enough water to protect their trunks with sap. The drought-induced devastation of the Coulter pines due to the beetles has allowed some landowners in the Volcan Mountains to the immediate north of Julian to obtain exemptions from filing timber-harvest plans. These plans are normally required under the California Environmental Quality Act and effectively allow the state to regulate the logging practices exercised on a parcel of land, raising fears in Julian that overlogging might be technically permissible in light of the Coulter pine disaster.
In recent decades, Julian has become a quaint mountain resort, with most businesses oriented toward tourism and not local services. The main area of town narrowly escaped destruction in the 2003 Cedar Fire that burned much of the surrounding area.
In 2004, an interviewing journalist noted that up to a third of Julian’s population had been affected by property losses associated with fire. The local fire district had recently removed property-tax benefit fees, making reconstruction more difficult for residents devastated by fires. Drought and infestation of the local forests by pine bark beetles was observed to exacerbate the fire season’s stressing effect on the community.
Fire disruptions as of 2004 were observed in Julian to have caused the disappearance of populations of red-winged blackbirds, acorn woodpeckers, white-crowned sparrows, lesser goldfinches, scrub jays, Steller’s jays, nuthatches, or black-headed grosbeaks.
In 2017, the Julian Arts Guild opened an art gallery in downtown Julian, Julian Arts Guild Gallery, where local artists and artisans display their works.
On April 14, 2025, a magnitude 5.2 earthquake struck 2.5 miles miles south of Julian at around 10 a.m. Minor damage occurred, but no injuries. Some roads were closed because of fallen boulders.

Climate
Julian experiences more extreme temperatures and greater precipitation than much of southern California. It also receives snow annually, which accumulates the most in February and March. This attracts people from San Diego and other coastal cities, where snow is a once-in-a-lifetime event. As is typical in southern California, the summer has the driest months, but with a number of monsoonal storms from the southeast. Average yearly snowfall from 1991 to 2020 has been .
According to the Koppen climate classification system, Julian experiences a hot summer Mediterranean climate (Csa).
