Penngrove is a census-designated place (CDP) in Sonoma County between Rohnert Park to the north and Petaluma to the south, and east of Highway 101. Originally, it was an active freight station for the Northwestern Pacific Railroad due to robust egg and chicken farming enterprises. According to the San Francisco Examiner, such farms at the time reaped rewards greater than those of the gold miners.
Today, with a population of approximately 2,500, this is a quiet little community with lots of history to claim. Home of the annual Fourth of July Parade, sponsored by the Penngrove Social Firemen, it is a throwback to a simpler time. Many historical buildings are still erect and in use including the Penngrove Community Church (1898), Penngrove School (1926) and the Penngrove Community Clubhouse, built during World War I for Red Cross workers.
Penngrove was once a major source of paving stones, and many of the major Bay Area streets are paved with Penngrove resources.
Activities typical of Sonoma County abound here as well: wine tasting, hot air balloon rides, hiking, biking and rafting. It’s a quaint and charming community that feels like a world unto itself.
