Guests of The Inn Above Tide in Sausalito are just a short drive from the Marin Headlands’ hidden natural treasures, including Tennessee Lagoon. Nestled just steps from the Pacific Ocean and adjacent to the scenic trail leading to Tennessee Beach, this tranquil, man-made freshwater lake supports a surprisingly rich array of wildlife. It’s the perfect spot for visitors who want to enjoy birdwatching, photography, or simply a quiet moment surrounded by nature before heading to the beach.
A Unique Ecosystem by the Ocean
Tennessee Lagoon is a rare sight along the California coast — a freshwater lake located within earshot of the crashing waves. Originally created as part of a ranching operation, the lagoon has since evolved into a thriving habitat for a variety of bird species, amphibians, and aquatic plants. The combination of freshwater and the nearby saltwater environment creates a unique ecosystem where different species overlap, making it a fascinating stop for nature lovers.
Birdwatching at Tennessee Lagoon
The lagoon is particularly popular with birdwatchers. Shorebirds such as snowy egrets, great blue herons, and American coots are frequent visitors, while red-winged blackbirds and song sparrows add a splash of color to the reeds and marsh grasses. In winter and during migration seasons, the lagoon attracts ducks, geese, and other waterfowl, making it an excellent year-round birding destination.
If you’re patient, you may also spot birds of prey such as northern harriers gliding low over the grasses or an osprey diving for fish. A good pair of binoculars or a telephoto lens can help you fully appreciate the variety of species that use the lagoon as a resting and feeding ground.
Wildlife Beyond the Birds
While the birdlife is the main attraction, Tennessee Lagoon also supports amphibians such as Pacific tree frogs, as well as small fish and aquatic insects that form the base of its food chain. The surrounding vegetation provides cover for small mammals and serves as a nursery for native plants. The mix of open water, marsh, and nearby coastal scrub creates a vibrant patchwork of habitats in a relatively small area.
Combining the Lagoon with a Visit to Tennessee Beach
One of the best things about Tennessee Lagoon is its proximity to Tennessee Beach. The lagoon sits just inland from the shoreline, separated from the Pacific by a low sand berm. This means you can enjoy a morning of wildlife watching at the lagoon and then take a short stroll to the beach for ocean views and the chance to explore the site of the S.S. Tennessee shipwreck at low tide.
The trail from the Tennessee Valley parking lot passes alongside the lagoon before continuing on to the beach, making it an easy and rewarding addition to any visit. Benches along the way offer spots to pause and take in the scenery.
Photography Opportunities
For photographers, Tennessee Lagoon offers a variety of compositions — from close-up shots of wading birds reflected in the still water to wide landscape images capturing the lagoon, grassy banks, and ocean beyond. Early morning and late afternoon often provide the best light, while seasonal changes bring new colors and wildlife into frame.
