Woodside Store was built back in the 1850s by two pioneers who came to California for the gold rush. At the time it was the only stagecoach stop between San Francisco and Santa Clara, and it carried all the essential items that travelers riding between cities might need. The store has been restored, inside and out, to look exactly as it did centuries ago. You can call the museum ahead of your trip to book tours.

The Woodside Store, also known as Tripp Store, is located at 3300 Tripp Road at Kings Mountain Road in Woodside, San Mateo County, California. It has been listed on the National Register of Historic Places since 1985 and was designated a California Historical Landmark in 1949. The store's history dates back to October 1849 when Matthias Alfred Parkhurst purchased land in the area and began a shingle-making and lumber business with his partners, including Robert Orville Tripp. The store was established in 1853, originally serving the needs of lumbermen and settlers during the Gold Rush era. Dr. Tripp became the sole operator of the store after Parkhurst's death in 1863, running it until his own death in 1909. He was a well-known figure in Woodside, holding various public offices. The San Mateo County Historical Association acquired the store in the 1940s, and it was restored to its 1880s condition by 1994.
