      Belmont is a small, mostly residential city in San Mateo county. Its notability for mountain biking lies in a little gem of a park called Waterdog Lake Park (often also referring to the adjoining Hidden Valley Open Space Preserve). Many of the trails in this park have been built and maintained by mountain bikers, lending to a surprisingly dense and interesting trail network for such a small area.
