• Lake Merced


    The largest of San Francisco’s three natural lakes, Merced was once a single body of water, but it is today divided into North, East, South, and Impound lakes. Bird-watchers mark their sightings here by a few main landmarks: the concrete bridge, the boathouse, the wooden bridge, and Sunset Circle. You can visit them all by bicycle or walking on a flat, mostly paved trail of about 5.4 miles.
