The Marina at Pier 39 is a working waterfront marina in San Francisco, California, celebrated for its resident sea lions, sweeping bay views, and easy access to iconic landmarks.
The Marina at Pier 39 sits at the northeastern edge of San Francisco, tucked into the concourse of one of the city's most visited destinations. The marina itself accommodates several hundred vessels, from modest day-sailers to larger cruising yachts, and serves as a working harbor with pump-out stations, fuel, and full guest berth services.
The spot is perhaps best known for its spontaneous residents: a large colony of California sea lions that claimed the K-Dock floats in the early 1990s and never left. Watching them pile atop one another, argue for space, and slide into the bay is a genuine San Francisco spectacle. Nearby, you can explore Aquarium of the Bay for an underwater look at the same waters these animals call home.
Beyond wildlife, the marina is a natural launching point for boat tours across the bay, giving visitors a water-level perspective on the city skyline and surrounding landmarks. The broader Fisherman's Wharf neighborhood offers fresh seafood, sourdough bread, and decades of maritime heritage within easy walking distance.
Few places in San Francisco compress so much bay life, city history, and natural drama into a single pier, making The Marina at Pier 39 a worthwhile stop for any visit to the waterfront.
Visit in the morning when the sea lions are most active and the bay light is ideal for photographs.
