Portola Valley is a town in San Mateo County, California. Located on the San Francisco Peninsula in the Bay Area, Portola Valley is a small, wealthy community nestled on the eastern slopes of the Santa Cruz Mountains.
Portola Valley was named for Spanish explorer Gaspar de Portolá, who led the first party of Europeans to explore the San Francisco Peninsula in 1769.
The Native Americans already present were Ohlone and specifically the group (or groups) known as Olpen or Guemelento but these were later moved to Mission Dolores and Mission Santa Clara de Asís which claimed the land and peoples. The area's written history dates back to 1833, when a square league of land was given to Domingo Peralta and Máximo Martínez by Governor José Figueroa to form the Rancho Cañada del Corte de Madera. In those days it was used for lumbering and cattle grazing.
By the 1880s Andrew S. Hallidie, a wire rope manufacturer, had built his country home of Eagle Home Farm in what is now Portola Valley. He built a 7,341 foot long aerial tramway from his house to the top of Skyline in 1894 though it was removed after his death in 1900.
In 1886 the name Portola-Crespi Valley was bestowed on the area from the then community of Crystal Springs (now under Crystal Springs Reservoir to the then community of Searsville (in the area of the present day Jasper Ridge Biological Preserve); Crespi is for Juan Crespí, a Franciscan friar with the Portolà expedition.
The town was incorporated in 1964. Bill Lane was the first mayor.
Portola Valley is located on the San Francisco Peninsula on the eastern slope of the Santa Cruz Mountains.

The Alpine Inn, also known as Casa de Tableta, Rossotti's or Zott's, is one of the oldest existing drinking establishments in California; it started around 1852 when Felix Buelna built it as a gambling house. The first two-network TCP/IP transmission was between a specialized SRI van and ARPANET on August 27, 1976; the van was parked next to the Alpine Inn and wires were run to one of the picnic tables. In 2018, the inn was acquired by new owners, who closed it temporarily for remodeling. It was re-opened in August, 2019.
Villa Lauriston, an estate located at 5050 Alpine Road and encompassing almost 29 acres, was initially commissioned by James Graham Fair, the founder of Fairmont Hotels and Resorts.
