Discovery Guide


Hudeman Slough to Black Point

Though this portion of the Bay Trail is not fully complete, there are four segments open to explore the marsh plain, sloughs, and mudflats of the northern San Pablo Bay: the Tubbs Island Trail, Sears Point Bay Trail, Sonoma Baylands Bay Trail, and the Port Sonoma Marina Trail. Note that the Tubbs Island Trail can only be accessed from the eastbound direction on Highway 37 and does not allow dogs.

Corte Madera, Tiburon & Strawberry Point

For this trail, bikers can travel south down the Tiburon Peninsula on Paradise Drive for beautiful views of the Bay. Hikers can begin in downtown Tiburon and walk along an old railroad alignment for around 3 miles before reaching Blackie’s Pasture where you can visit the statue of Blackie the horse. For more of an adventure, head to Strawberry Point and hike the Shoreline Spur Trail for even more bayshore views.


Native Nursery Tour

Save The Bay grows between 35-100 thousand plants every year for our restoration projects. This means that every year we get to watch plants move through the beginning of their life cycle. We grow about 30 different native species, each with its own unique life cycle. Come tour our native plant nursery and learn about a very special marsh plant that you can see all over the Bay: marsh gumplant, also called by its scientific name, Grindelia stricta.

Pied-billed Grebe


Grab a pair of binoculars and head to Las Gallinas Sanitary District Wildlife Area. Wastewater treatment plants often provide birders excellent opportunities to see marshland species from levee trails encircling ponds, and Las Gallinas includes wildlife viewing as part of its mission. Numerous waterfowl and raptors including Cackling Goose, Erurasion Wigeon, Osprey, Golden Eagle, Ferruginous Hawk, four species of falcon and the Great Horned Owl have been spotted here.

Redesigning Highway 37: A Regional Model for Multi-benefit Climate Resilience

If your Bay Day adventures lead you to the shoreline trails along areas of the recently restored San Pablo Bay National Wildlife Refuge, you’ll definitely rely on Highway 37 to get there. You may not know it, but Highway 37 is actually one of the roads in the Bay Area most threatened by sea level rise. In fact, this narrow and chronically congested highway already suffers from flooding like in 2017 when it was closed for nearly a month after especially heavy rains. With rising tides due to climate change, in the coming years large stretches of this critical connection will be regularly underwater. But if done right, solving these flooding and congestion challenges could also be the key to restoring even more tidal marshes in the north bay – a lot more.

An effort being led by the Sonoma Land Trust is working to redesign Highway 37 to create a win for both the drivers who rely on it, and for the Bay by reconnecting more than 20,000 acres of restorable tidal marsh that are currently cut off by the highway. Ultimately, this effort is working with Caltrans to elevate Highway 37 along a causeway. Doing so will allow for congestion relief and ensure the new road is resilient to rising tides, while also allowing for the full restoration of the San Pablo Baylands.

To achieve these goals, we have to change how we measure the costs and benefits of an infrastructure project. Investing in an elevated Highway 37 is not just a simple road improvement project but is actually a regional model for multi-benefit climate resilience that will help the state meets its goals for using nature to fight climate change. And, since this is one of the largest potential shoreline restoration projects remaining in the Bay, if successful a future Bay Day visit to the area may have even more to offer.

Discovery Guide


Alviso to Newark

Alviso is a historic waterfront town in the city of San José, located at the southernmost part of the Bay.  The former marina has been restored back into wetlands and houses a variety of trails. As you explore you can see wetlands, brackish and freshwater marshes, and salt ponds. The nearby Environmental Education Center off of Grand Boulevard exhibits some interpretative displays of wetland wildlife and has its own 4.5 mile loop trail surrounding a restored salt pond.

Ravenswood Slough to Alviso

This trail begins at Bedwell Bayfront Park, heading southward into the Don Edwards San Francisco Bay National Wildlife Refuge and finishing at Alviso Marina County Park. From here you can explore the Ravenswood Open Space Preserve, discover the Lucy Evans Baylands Nature Interpretive Center, and visit the nearby Sunnyvale Baylands Park which features seasonal wetlands and grassy uplands that are great for picnicking.


Monitoring Restoration Sites

Save The Bay’s Habitat Restoration Team is currently monitoring restoration sites. In order to know where to focus our work, we systematically observe our site looking for a variety of species and habitat structures. This process is called monitoring and in this video, we’ll show you what monitoring looks like. Modeling our restoration strategy around the natural processes of these native habitats gives them the best chance for success well into the future.

Picnic at Sunnyvale Baylands Park

Sunnyvale Baylands Park features fields to sit and relax on, playgrounds for the children, and beautiful trails to observe preserved wetlands. Baylands Park provides over seventy acres of developed parkland offering active recreation, pathways and picnic areas for families and large groups. An additional 105 acres of seasonal wetlands is protected as a Wetlands Preserve providing habitat for plants and wildlife.

Large-scale Restoration near Bedwell Bayfront Park

On the southeast side of Bedwell Bayfront Park, Save The Bay is using innovative restoration techniques to create a nature-based solution to flooding and sea level rise. The 9.6 acre Ravenswood horizontal levee project offers a glimpse of what 21st century levees could look like in the Bay Area and beyond. By creating a wide, gently sloping, vegetated buffer of land, horizontal levees help prevent water from moving inland and protect communities from flooding and sea level rise. The restored native habitat will also provide crucial refuge for local wildlife.

For this large-scale project, Save The Bay is combining tried and true restoration methods of planting native species by hand with new strategies that utilize farming equipment to quickly spread rhizomes and seed mixes throughout the area. The Ravenswood horizontal levee is an important evolution in levee design and restoration technology, offering an example of how future shoreline adaptation projects can build resilience against climate change.

With recreational trails connecting to Bedwell Bayfront Park, Ravenswood is an easily accessible site to enjoy nature at the edge of the Bay.

Urban Greening in San José

As climate change intensifies across the globe, Bay Area residents are grappling with the immediate impacts in the form of intense heat waves, unhealthy air quality and more frequent flooding, caused by rising sea levels and erratic weather patterns. For cities in the Bay Area, especially low-lying and shore-adjacent cities like San José, the importance of building climate resilience is becoming increasingly clear.

One of the most effective and transformative methods of building climate resilience is through urban greening. Urban greening incorporates nature back into urban areas, especially in vulnerable communities that have been historically underserved, in order to improve environmental health and community livability. By including features such as rain gardens, bioswales, and trees in planter boxes, cities can use natural systems to address some of the negative impacts of climate change.

The benefits of urban greening are vast. It can reduce the urban heat island effect, improve air quality, and buffer communities against flooding. Additionally, it creates more tranquil public spaces, which in turn can encourage active transportation and improve mental health. This nature-based, multi-benefit approach will not only protect the health and safety of residents, but can also make the city a more equitable and desirable place to live, work, and play.

San José has already made some investments in green infrastructure. The Park Avenue Green Streets Pilot Project, along Park Avenue between University Avenue and Sunol Street, includes 6,500 square feet of curbside rain gardens. These rain gardens replaced impermeable asphalt, and will help absorb and filter stormwater from surrounding roadways. On Chynoweth Avenue, 5,600 square feet of curbside rain gardens replaced what was once asphalt. The rain gardens host drought tolerant plants and tree wells to absorb and filter stormwater. Take a walk for your Bay Day Challenge to see urban greening in action in San José!

Climate Resilience in Oakland and Beyond

The City of Oakland is currently updating its General Plan, a blueprint that will guide the City’s development in the coming decades. Over the past months, Save The Bay has been advocating for climate resilience to be prioritized in the General Plan Update process. This has included meeting with City staff and community stakeholders, as well as attending outreach events and submitting comments on the General Plan elements.

One major milestone in our Oakland General Plan work was the passage of a citywide resolution incorporating climate resilience and adaptation measures into the General Plan update. This resolution, sponsored by Councilmember Dan Kalb and President Pro Tempore Sheng Thao, called for the General Plan to work towards “healthy, resilient communities that are equipped to thrive in the face of climate hazards.” It directs City staff to prioritize environmental justice outcomes for frontline communities, and requires climate resilience to be incorporated into housing, infrastructure, and other related issues.

This Oakland resolution will help ensure that the city is resilient to climate impacts in the coming decades. It also serves as a model of climate resilience planning throughout the Bay Area. If cities across our region incorporate resilience into their planning processes, it will move us towards a safer and more environmentally just Bay Area.

A Decade of Habitat Restoration at Eden Landing

3 people showing off their pile of pulled weeds

Eden Landing Ecological Reserve (ELER) is one of our staff members’ favorite sites for viewing wildlife, exploring transition zone habitats, and witnessing change on the landscape. This 6,400-acre reserve of restored salt ponds, marshes, and upland habitats has been a restoration location for Save The Bay for over a decade. We partner with the California Department of Fish and Wildlife to complete this work and have successfully restored 8 transition zone sites, totaling over 6 acres.

In the spring of this year, we launched into work on our ninth site! A new site begins with plenty of weeding: removing species that grow quickly and take over the landscape to make more room for natives. With the help of volunteers, we removed over two tons of weeds from our new site this spring. As the (hopefully) rainy season approaches, we will begin planting a diverse selection of native species, creating habitat for wildlife, and providing many additional ecosystem services.

If you head out to Eden Landing this month, walk along the road from the parking lot toward the kayak launch. The left side of the trail is a site we restored ten years ago. The right side is our new site. Take your time to observe the similarities and differences between the two. Send us any questions that come up as you explore.  Enjoy!
