      Waterdog Lake/Hidden Canyon Park contains 260 acres of open space and a multi-use trail system located 25 miles south of San Francisco. It is a place for fun, adventure, commune with nature, and service. While the City oversees its management, volunteers have long contributed to trail building and maintenance efforts.

      William C. Ralston, founder of the Bank of California, originally commissioned the lake to collect spring water to funnel to his summer home—now known as Ralston Hall Mansion. Following Ralston’s death, the Sisters of Notre Dame de Namur acquired the land, leasing it to the City of Belmont in 1965. In 1978, John S. Brooks dedicated an additional 51 acres to the City.
