Sawyer Camp Trail is also referred to as Crystal Springs by San Jose and San Mateo, California residents. Each year Sawyer Camp Trail sees about 300,000 people. It is considered the most popular San Mateo County trail, though there are certainly other trails in the area. The trail allows visitors to reach Crystal Springs Watershed using the linear trail. There are a few areas that have been expanded in order to make the trail uninterrupted. No motorized objects are allowed on the trail. It is also a multi-use trail from San Bruno City and Woodside Town.
In October 2010, the Crystal Springs Dam Bridge was closed to traffic in order to renovate the bridge. Automobiles and bicycles have to access Sawyer Camp Trail from an alternative southern route. Once the bridge has been replaced it will be opened again for a way to get to Sawyer Camp Trail parking. The area was home to Shalshone Indians for centuries until Spanish and other European settlers began to infiltrate California. Sawyer Camp Trail was named after Leander Sawyer who once set up a camp around the area. In the 1850s to 1860s the trail was meant for grazing cattle.
