San Francisco Bay Trail

Plans for development of the Bay Trail call for a continuous 500-mile network of bicycling and hiking trails that will encircle San Francisco Bay, San Pablo Bay and the Carquinez Strait.

MTC has been a major funder of the Bay Trail project. When completed, the trail will connect communities with the shoreline and with each other.

340 miles have already been developed! The trail now touches all nine Bay Area counties, passes through 47 cities and crosses four-and-a half toll bridges.

Hikers, joggers, bicyclists, skaters and wheelchair riders can all enjoy the Bay Trail.

The opportunities for wildlife viewing and environmental education are many. The Bay Trail also serves as an important commute alternative for bicyclists.

The Bay Trail Project, a nonprofit organization spearheaded by ABAG, coordinates efforts for the trail by:

  • Raising funds for trail construction and maintenance
  • Ensuring consistency with the adopted plan
  • Providing technical assistance
  • Enlisting public participation in trail-related activities
  • Publicizing the Bay Trail

The Bay Trail originally was envisioned as a “ring around the bay” by then-state Sen. Bill Lockyer, whose Senate Bill 100 was passed into law in 1987.

The Bay Trail connects to numerous transit facilities, including ferry terminals, light-rail lines, bus stops, and Caltrain, Amtrak and BART stations.

The Bay Trail eventually will cross most of the major toll bridges in the Bay Area.
