Perris is a city in Riverside County, California, United States, located 71 miles (114 km) east-southeast of Los Angeles, California, and 81 miles (130 km) north of San Diego, California. It is known for Lake Perris, which hosts a variety of flora and fauna. The city is most widely recognized for having many choices involving aerial activities, such as skydiving and hot-air ballooning. Perris is within the Inland Empire metropolitan area of Southern California.
The Perris Valley was actively settled in the 1880s, a boom period for Southern California. Prior to 1880, the land was used for pastures. The coming of the California Southern Railroad led to the founding of the city around the new depot. The California Southern was built through the future town site in 1882 to open a rail connection between the present day cities of Barstow and San Diego. Due to a land title dispute at Pinacate, most of its citizens moved two miles north on the railroad and established Perris in 1885. The city is named in honor of Fred T. Perris, chief engineer of the California Southern Railroad.
