Waterfront Park Near Me: Heron's Head Park Marsh Trail in Bayview

Heron's Head Park at Cargo Way and Jennings Street is a free 22-acre Bayview marsh peninsula with a bay trail, picnic grills and a LEED Platinum EcoCenter.

If your idea of a waterfront park near me is less about lawns and more about tide channels, marsh grass and wading birds, head to Heron's Head Park in Bayview. The Port of San Francisco's peninsula pokes into the bay where Cargo Way meets Jennings Street, and it feels nothing like the polished northern waterfront. It is flat, windy and quietly wild, and on a calm morning the only sounds are gulls, rustling cordgrass and the distant hum of the port.

A Peninsula Made From Fill

Heron's Head did not start as nature. According to the Port, the peninsula is about 22 acres of fill that the Port placed in San Francisco Bay during the 1970s, and locals long knew the spot as Pier 98. In 1999 the Port turned it into a park after crews cleared away some 5,000 tons of garbage and debris, as the San Francisco Chronicle reported, to make room for picnic areas, paths and native plants. Today about 8 acres of the park are intertidal marsh.

The name has nothing to do with a pier or a person. Seen from above, the Port explains, the peninsula is shaped like the head of a great blue heron, with the narrow tip forming the bill. Improvements finished in 2012 added better walking and bicycle facilities, and from 2020 to 2022 a restoration project planted more natives to slow erosion along the shoreline, which is why the edges now look fuller and greener than in older photos.

Birding Along the Marsh Trail

The Port notes that the park attracts more than one hundred bird species, which makes it one of the most rewarding birding walks inside city limits. A paved path and an unpaved walking trail lead out along the spine of the peninsula, with the marsh on one side and open bay on the other. Walk slowly at low tide, when the mudflats are exposed and herons, egrets and sandpipers feed along the channels. Binoculars make a huge difference here, and a zoom lens even more.

The trail is also a link in the San Francisco Bay Trail, the long regional path around the bay, and inside the park it crosses the Blue Greenway, the city's southern waterfront route. That means you can arrive on foot or by bike from the north, stop for an hour among the birds, and continue toward Bayview's other shoreline parks.

The EcoCenter, a Green Building on the Bay

Near the entrance stands the EcoCenter at 32 Jennings Street, a small education building that punches above its size. The nonprofit Literacy for Environmental Justice completed it in 2010 and handed it over to Port ownership in 2013. Designed by Toby Long Design, it was certified LEED Platinum in July 2013, and Bay Nature's story on its opening described it as environmental education off the grid. Inside, a classroom of about 660 square feet holds up to 55 people and can be rented for workshops and community meetings.

Picnic Sites and Rules for Groups

Heron's Head has three picnic areas, each with tables and barbecue grills and a maximum capacity of 40 people, so it suits a birthday or a family reunion as long as you plan for wind. The lawn covers 8,800 square feet and can host up to 500 people; shade tents are allowed there, but camping tents are not. A children's nature play area gives younger kids room to explore, and accessible environmental restrooms sit close to the parking lot. The lot itself is small, with 25 spaces, three of them reserved for disabled visitors.

Dog owners have their own corner too: the ButcherTown Dog Run sits within the park, so dogs can burn off energy without disturbing the birds out on the marsh. Keep them out of the wetland areas, where nesting birds and young plants are easily trampled.

Volunteer Saturdays in the Nature Area

One of the best ways to get to know the park is to help look after it. San Francisco Recreation and Park Department and the Port host a volunteer work party in the Nature Exploration Area every third Saturday from 10 am to noon; the October session fell on Saturday, October 17, 2026. Volunteers pull invasive weeds, mulch native plantings and tend the habitat, and it is a friendly introduction for newcomers to Bayview who want to meet neighbors.

How to Time a Visit

Tide matters more than the clock. Check a tide table and aim for a falling or low tide, when feeding birds crowd the exposed mud. Mornings tend to be calmer, while the afternoon wind can make the exposed tip of the peninsula feel cold even in October. Bring a windbreaker, sturdy shoes for the unpaved trail and water, since there is no cafe on site. Sunset paints the marsh gold, but the parking lot is small, so arrive early on weekends.

Getting to Cargo Way

Muni's 19 Polk and 44 O'Shaughnessy both run along Evans Avenue, with a stop at Evans Avenue and Keith Street, and the T Third light rail stops at 3rd Street and Evans Avenue. From any of these, walk east toward the water and follow Jennings Street to Cargo Way. Cyclists arriving on the Bay Trail can lock up near the EcoCenter. For general questions, the Port's reception desk answers at (415) 274-0400; report maintenance issues to 311.

Continue to India Basin

Heron's Head pairs naturally with India Basin Waterfront Park at 900 Innes Avenue, a short ride southeast along the shore. There you will find an 1875 shipwright's cottage turned welcome center, new public piers and a weekend food pavilion, which makes it the natural lunch stop after a morning of birding. Taken together, the two parks show how Bayview's industrial shoreline is slowly being handed back to the public.
