The Parks Division manages the Andrée Clark Bird Refuge, a 42-acre open space park that includes a 29-acre lake that is an artificially modified estuary that supports brackish wetlands. Three islands are located in the lake. The park provides passive recreation opportunities such as bird watching, hiking, and biking. Boating and fishing are prohibited, as is feeding the wildlife. The Bird Refuge is a scenic resource with views to and from scenic highways (East Cabrillo Boulevard and Highway 101) and provides a view of aquatic and terrestrial habitats.
The eastern and southern perimeter of the Bird Refuge includes a Class I bike path around the lake that extends from the Bird Refuge, along the ocean and Harbor, to Shoreline Park. The Bird Refuge includes walking paths along the northern shore and three viewing platforms that provide excellent opportunities for bird and other wildlife observation. Over 200 species of birds have been observed at the Bird Refuge. Native and non-native turtles can be observed basking on floating vegetation and along the perimeter of the islands. Sensitive wildlife resources present at the Bird Refuge include: tidewater goby, southwest pond turtle, and several birds protected under the Migratory Bird Treaty Act.
