The first European land exploration of Alta California, the Spanish Portolà expedition, passed through the area on its way north, camping for three days near today's San Gregorio, October 24-26, 1769. Franciscan missionary Juan Crespi noted in his diary, "This is a fine place, with good lands and an abundance of water, where a good mission could be placed". No mission was ever established here, however. The string of Spanish Missions established over the next 50 years followed a more inland route through San Jose.
Named after Pope Gregory I (Saint Gregory the Great), San Gregorio was a booming town in the 1850s, when wealthy San Franciscans would travel to the San Gregorio House by stagecoach to enjoy fishing, hunting, sea bathing, and boat races. The building still stands, but is no longer a functioning hotel. However, the San Gregorio General Store has been thriving since 1889. It houses eclectic items for sale, from books to clothing to groceries. Its bar serves sarsaparilla and hot chocolate as well as alcoholic beverages, and is frequented by local musicians. The original stagecoach stop stands across Highway 84 from the store. Recently, San Gregorio has become a favorite among filmmakers looking for a "funky" historical backdrop.
