The San Francisco Public Utilities Commission will open the new six-mile Skyline Watershed Ridge Trail to the public Monday, giving visitors access to a portion of the Peninsula Watershed in San Mateo County.

The trail opens at 6 a.m., and a free permit is required for entry. It runs along SFPUC property parallel to Skyline Boulevard and extends south from Highway 92.

The trail is the newest addition to the Bay Area Ridge Trail, bringing the regional network to 413 completed miles of its planned 550 miles.
