Leo J. Ryan Memorial Park is Foster City's main public waterfront space, running along the San Francisco Bay shoreline with open views across the bay to the hills of Oakland and Berkeley. The park has a promenade, a marina with boat launches, a model yacht pond, and wide grassed areas for picnics and sports. On clear days the views extend to the San Mateo-Hayward Bridge.
The park is particularly good at dusk, when the bay turns gold and the bridge lights come on. Bird life on the mudflats and wetland areas is varied — egrets, herons, and shorebirds are common. The promenade connects to a network of bayfront trails that extend north and south along the peninsula.
