San Pablo Bay National Wildlife Refuge provides numerous recreation opportunities that includes wildlife viewing, wildlife photography, hiking, boating, fishing, and hunting. Regulation of these recreation activities allow for public enjoyment of the refuge while still protecting the wildlife and habitats.
San Pablo Bay National Wildlife Refuge is open year-round during daylight hours. Check with the refuge office for the latest update on trail closures, wildlife concerns, maintenance and management activities.
TRAILSSan Pablo Bay National Wildlife Refuge offers multiple hiking and bicycling trails (see Trail Map):
Tolay Creek/Lower Tubbs Trail: The parking lot is located 0.65 mile east of Highway 37/121 intersection. From the parking lot, this trail follows along the Tolay Creek for 2.5 miles before reaching Lower Tubbs Island. The trail once circled Lower Tubbs Island, however, during the 2014 South Napa Quake, breeches were formed in the levee making two sections of Lower Tubbs impassable. Once you reach Lower Tubbs Island, the trail offers beautiful views of salt marsh habitat and San Pablo Bay. This is one of the few places in the San Francisco Bay Area where one can feel remote from the hustle and bustle of a metropolitan area. Wildlife observation and photography are encouraged. Please stay out of closed areas to minimize disturbance to plants and animals.
Cullinan Ranch Trail: The parking lot is located 3.4 miles west of Marre Island on Highway 37. From the parking lot, the trail goes north for 1.3 miles until you reach South Slough. The trail offers views of Cullinan Ranch to the east and CDFW Pond 1 to the west. Both areas may have numerous waterfowl and shorebirds foraging and resting.
Sears Point: The parking lot is located at 7699 Reclamation Road in Sonoma. This parking lot allows for access to four trails:
BOATINGBoat access to the open water and navigable sloughs of San Pablo Bay provides opportunities for fishing, wildlife observation, and wildlife photography on the refuge. There are no motorized boat ramps on the refuge. Ramps are available at the Vallejo public marina near Brinkmans marine and at Port Sonoma near the Petaluma River.
