The San Jacinto Valley as seen from the San Jacinto Mountains. The bright street in the middle is Florida Avenue in Hemet.

The San Jacinto Valley is a valley located in Riverside County, in Southern California, in the Inland Empire. The valley is located at the base of the San Jacinto Mountains in the east and Santa Rosa Hills to the south with the San Gorgonio Pass to the north. The average elevation is 1,500 feet (460 m), with the highest points in the foothills south of Hemet and the western slopes of the San Jacinto Mountains. It is home to two cities, Hemet and San Jacinto, and several unincorporated communities. According to the 2020 census, the valley has a combined population of over 190,000 residents,[1] including more than 143,000 residents within the city limits of Hemet and San Jacinto.[2] The valley is also where the story and play "Ramona" was set; the story was written after author Helen Hunt Jackson visited the valley in the 1880s.[3] The valley is also known for being an area of agriculture, which has given way to more urbanized development.


The first native people settled in the San Jacinto Valley thousands of years ago.[4] Later, the Serrano and Cahuilla people arrived, whose villages were located along and near streams and springs. They were hunters and gatherers and they subsisted primarily on small game and acorns. The Soboba Indian Reservation, just east of San Jacinto, is now the home to the descendants of some of these people. The first Spanish explorers entered the San Jacinto Valley in the early 1770s. In 1774, and again in 1775, Colonel Juan Bautista de Anza led two expeditions up from Mexico, crossing the Colorado River at Yuma and continuing across the Borrego Desert and up Coyote Canyon. For a few years, the Valley was on the main overland route to California.[4] In the early 19th century, the area became a cattle ranch for the Spanish Mission San Luis Rey, which is located in the modern-day city of Oceanside. The area was known as Rancho San Jacinto. When the missions were broken up by the Mexican government, the land was given to José Antonio Estudillo in 1842. This land grant eventually became the towns of San Jacinto and Hemet.[5]


There are two incorporated cities in the San Jacinto Valley, Hemet and San Jacinto. The two cities in the valley have experienced significant growth since the 1980s, and make up one of the fastest-growing areas in the state of California and Riverside County.[citation needed]


Hemet has an area of about 29.3 square miles (76 km2), and a population of 89,833 as of the 2020 census. Hemet was founded in 1887 and was incorporated on January 20, 1910. The city is home to the Ramona Bowl which is where "Ramona", the official outdoor play of California, is performed. Hemet is located at the southern end of the valley. The city is home to the Western Science Center, and Diamond Valley Lake. This city was also named a Tree City USA by the National Arbor Day Foundation, and is home to the only hospital in the valley.

San Jacinto

The "S" on the mountains just north of San Jacinto

San Jacinto has an area of 26.1 square miles (68 km2), most of it land. The population was 53,898 according to the 2020 census. It was named after Saint Hyacinth and is located at the north end of the valley. The city was founded in 1870, and was incorporated on April 9, 1888, making it one of the oldest cities in the county. The city is also home to Mt. San Jacinto College, a community college which has served the valley and the Inland Empire since 1965. The city is also planned to be the location of the eastern terminus of Mid County Parkway, a new transportation corridor in that will link to I-215 in Perris.[6]

Unincorporated areas

Valle Vista

Valle Vista is an unincorporated area east of Hemet that extends south to Bautista Canyon and to the east to the base of the San Jacinto Mountains.

Fairview Avenue, which runs from Bautista Canyon to the city of San Jacinto, is part of the old historic Juan Bautista de Anza National Historic Trail, an old trail that went from Nogales, Arizona on the U.S. and Mexican Border, to a Presidio in San Francisco. This was one of the first overland routes to California.[4] The area will possibly be annexed by Hemet in the near future according to the proposed land use map on the City of Hemet's general plan website, but since the general plan is still under draft, this may not necessarily happen.[7]

The valley is served by a community college. Mt. San Jacinto College has served the valley since 1963. The college district was created in 1962 by a vote of the citizens of Banning, Beaumont, Hemet, and San Jacinto. The college enrolled its first students in the fall of 1963, holding classes in rented facilities. The San Jacinto Campus was opened in 1965 with two buildings and has grown into a full college campus serving the students and the community. In 1975, the residents of Temecula, Lake Elsinore, Perris and adjacent areas voted to join the Mt. San Jacinto Community College District, increasing the college’s area to the present 1,700 square miles (4,400 km2). The San Jacinto Campus has been master-planned and essentially will be rebuilt over the next 15 to 20 years to accommodate 12,000 to 15,000 students. In the fall of 1993, the Alice P. Cutting Business & Technology Center opened to students with new laboratories for Business, Computer Information Science, Engineering Technologies, Electronics and Photography. In the fall of 1995, a state-of-the-art music building opened on the San Jacinto Campus.[11][12]

Winchester Patterson House

The Patterson House was built in 1891 to replace a former adobe structure. The house measures 30 feet by 30 feet and is constructed of brick. The house is presently owned by The Winchester Historical Society of Pleasant Valley. The house is the oldest private residence still standing in what is now known as the community of Winchester. The Patterson family, John, wife Maria, daughters Tilla, Ida, and Jessie, and son Clarence, arrived in what was known as Rockhouse in 1883. They had traveled from Yountville through Los Angeles to come to their new home. The area they settled in was soon to become known as Pleasant Valley and later in 1887 as Winchester. As they passed through Los Angeles, Maria gathered pepper tree seeds which she planted at their new home. Some of these trees are still standing today. The family would soon become very influential in many aspects of the communities’ growth and prosperity. Listed below are some of the family’s accomplishments:

John Patterson

Nearby Museums

The Patterson House is a museum in Winchester, and is the oldest building in the town. It is located just off Highway 79 (Winchester Road), on the southeast corner of Patterson Avenue and East Grand Avenue. The residence was built by Winchester pioneer John Patterson, over the ruins of an adobe home that was the headquarters of a Mexican rancho before 1850. Some museum visitors have claimed to experience poltergeist activities including phantom knocking, doors opening, and objects moving. Some claim it is the spirit of Lloyd Patterson, who died in the house of tuberculosis as a young man in the early 1900s.[18][19]

The San Jacinto Valley Historical Connection is an online resource spawned from community interest in retaining the valley's history.[20] In Hemet, the Historic Harvard District holds special events thought the year.[21] In San Jacinto, one can find several historic homes on Main Street including the Vosburg Hotel.


State highways

Two state highways make their way through the valley: SR 74 and SR 79.

SR 74 begins in San Juan Capistrano at Interstate 5, heading through rural, mountainous portions of Orange County before reaching Riverside County. It descends into the city of Lake Elsinore and later reaches Perris, eventually overlapping with I-215 for roughly two miles. Continuing east, it passes through Romoland and Homeland, entering the San Jacinto Valley as Florida Avenue. At the eastern end of the valley, it begins to wind through the San Jacinto Mountains and eventually ends in Palm Desert.

SR 79 begins at Interstate 8, a few miles east of Alpine in San Diego County. It heads north to Julian and Warner Springs, eventually reaching Riverside County and the city of Temecula. After an overlap with I-15, SR 79 also makes its way into the valley. In Hemet, SR 79 overlaps State Route 74 (Florida Avenue), following it eastward for a few miles before heading north again through San Jacinto. It follows San Jacinto Avenue, North Ramona Boulevard, State Street, Ramona Expressway and Sanderson Avenue before going over the hills of Lambs Canyon and ending in Beaumont at Interstate 10.
