Bay Trail in Shoreline at Mountain View ParkThe San Francisco Bay Trail is a proposed 500-mile network of trails around the shores of San Francisco Bay. The Bay Trail runs through the 9 counties that surround the Bay. Over 340 miles of the trail have been completed. (See here for Bay Trail General Facts.) The trails run along the bayshore, salt ponds, creeks and sloughs, and marshes. The trails are ideal for biking, walking, jogging, nature-watching, and other activities. The trails are mostly flat, so are suitable for people of all physical abilities. The trail surfaces range from gravel roads, dirt levees, to paved landscaped paths. The paved paths are suitable for roller skates, baby strollers, and wheelchairs.

The environments range from enormous lonely salt ponds, to popular developed parks, to narrow paths near busy streets and commercial areas. Wildlife abounds, particularly waterfowl. These are excellent places for bird-watching. Ducks, geese, herons, egrets, pelicans, gulls, marsh hawks, cormorants, and shorebirds abound in these areas. Two endangered species make their homes in the pickleweed marshes along the Bay: the clapper (now Ridgway's) rail and the salt marsh harvest mouse.

Near the airports, the Bay Trail is an ideal area for watching manmade birds land and take off. Access to the Bay also makes the shorelines along the Bay Trail popular places for water sports such as fishing, swimming, and wind surfing. There are many public parks and recreational facilties along the trail, as well as homes, businesses, hotels, restaurants, and stores. The trail can be used for travelling to recreational spots, going to shop or eat, or even commuting to work. These activities will become even more possible once the entire Bay Trail is complete. With the public purchase of the Cargill salt ponds in the South Bay, even more trails are possible.

I've been biking around the southern Bay Trails. I've taken pictures of the scenery and made notes on the routes. My goal is to cover the Bay Trail from San Francisco International Airport, down the Peninsula, around the South Bay, and up the East Bay to Oakland International Airport. Here are the Bay Trail pages I've developed or am working on. They include the main trunk of the Bay Trail as well as feeder trails. The oldest pages are on my Bay Area Biking pages. From 1998 to around 2003, I created guided photo tours for the Bay Trail Project, which were hosted on their website and include trail descriptions. Those pages are marked with * below. The pages made before 2001 have pictures taken with film cameras and scanned from prints at low resolution. Starting from the end of 2001, I started taking pictures with digital cameras and posted pictures at higher resolution. The more recent webpages, starting in 2007, are hosted on my website, Some of the latest pictures are on Facebook albums. The webpages are listed below in geographic order, from north to south. The Facebook pages are in chronological order. All of these pages were developed strictly as a volunteer effort. If you would like to use any of these pictures, contact me.

My intent for doing these tours and pictures is to promote increased awareness and appreciation for the Bay Trail. Hopefully, as the Bay Trail brings more people in contact with the Bay, it will result in more support for preserving and restoring the Bay itself and its natural resources. Public and private support is needed to complete the Bay Trail. It is becoming one of the nations's truly great trail systems and will be a treasure for the Bay Area for years to come.

Update 2016: Note that my original Bay Trail guided photo tours are no longer available on the Bay Trail's website. They are available on the Internet Archive. The links below have been updated to point to the archived copies. Note that the internal page-to-page links, as well as many of the other links, on those pages may not work. These are archived copies, so I have no way to update them.

However, the links and information on those pages may be outdated and cannot be updated at this point. (See the Bay Trail's disclaimer.) The older the pages are, the more likely they are to have outdated information and stale links. Some areas may now be inaccessible, while new areas may be accessible. Park rules and hours may have changed. All conditions and information on these pages represent a snapshot in time and are subject to change without notice.
