THE PROJECT: Southern Skyline Ridge Trail

The San Francisco Public Utility Commission (SFPUC) is proposing to build a new 6-mile section of Ridge Trail in San Francisco backyard. This multi-use trail will take you along stunning ridgelines and through pristine forests in the Peninsula Watershed in central San Mateo County.

    Trail Project – Two separate and distinct trail sections:

    1. A new 6-mile trail and staging area south of Hwy 92, and
    2. An improved staging area and ADA accessible loop on the southern end of the Fifield Cahill Trail.
    Trail Access – Two distinct trail access systems:

    1. Public access by permit system (unsupervised, but restricted) on the new Southern Skyline Ridge Trail, routed along the ridgeline near Highway 35/Skyline Blvd. on less environmentally sensitive land; and
    2. Public access through a supervised docent program on the existing Fifield Cahill Trail. This docent program is currently in use and has full support of the Ridge Trail.

  • More Inclusive Access to the Outdoors: Public access in the outdoors matters now more than ever! Parks and open spaces around the Bay Area are experiencing record high visitorship, and trails are essential in these unprecedented times.
  • Strong Partner Support: For over 20 years, the Ridge Trail has collaborated with all the major land management agencies in the area including Peninsula Open Space Trust, Midpeninsula Regional Open Space District, Golden Gate National Recreation Area, and San Mateo County Parks.
  • Balancing Access and Natural Resources: The agencies involved are experts at balancing the desire for public access with the need for natural resource integrity, and this balance was carefully considered in designing the project.
  • Connecting The Ridge Trail: The addition of the Southern Skyline trail will bring us closer to connecting 100 continuous miles of Ridge Trail from northern Marin County deep into San Mateo county.

Dear Mr. Johnston –

I am a resident of [CITY]. I am writing on behalf of the Bay Area Ridge Trail in support of the proposed Southern Skyline Boulevard Ridge Trail Extension Project. I support the staff recommended project and access program. None of the project alternatives achieve the stated project goals, nor the Ridge Trail mission to create a continuous trail, for all users, that encircles San Francisco Bay.

Public access to the outdoors is important to me and my community. [OPTIONAL: ADD IN SENTENCE ABOUT WHY THIS IS IMPORTANT TO YOU!].

I support opening the southern Peninsula Watershed lands for more responsible and inclusive recreational use.


Thanks for supporting our work and the Southern Skyline Ridge Trail project!
