San Mateo County Birding Guide by Sequoia Audubon Society - Printed on October 30, 2026

An excellent spot to combine birding with a family outing, Twin Pines Park is adjacent to the Belmont Civic Center, and easily accessible from Ralston Avenue. What makes this park worthy of inclusion in this site guide, is the presence of Belmont Creek. This water feature creates a rich, accessible riparian that, with sustained attention, could well produce some migrant flocks and rarities.
That being said, Twin Pines Park defines the term "multi-use" park. There are artist studios, playgrounds, picnic areas, government buildings, and more - all nestled between a busy street (Ralston Avenue) and suburban houses. Traffic noise can be nearly constant; luckily it abates somewhat along Belmont Creek. However, the popularity of the park with families can produce a lot of noise too. Birders likely don't need this advice, but this is a spot where an early morning arrival is likely to net you better birds and less human interference than later in the day.
The mixed woods here include a lot of eucalyptus, as well as some oaks, creating good conditions for warblers and migrants. A good strategy here is to stay along the stream and the southwestern sections of the park. The pedestrian entrance from the southern border along O'Neill Street includes a bridge over Belmont Creek, and gives you immediate access to the best potential locations.

Twin Pines Park is located on the south side of Ralston Avenue, just west of El Camino Real (SR 82) and just east of Notre Dame de Namur University. You can enter the park from Ralston Avenue or from Sixth Avenue. Do not neglect the pedestrian entrance from O'Neill Street; as mentioned above this gives access to some of the best birding opportunities in the park, including the bridge over the creek.
Use of Twin Pines Park is free for casual use. There are areas and services available for rental for events; use this website to make reservations.
None posted, but daylight hours are fine. Remember that this park is in a neighborhood if you are engaging in early morning birding.
As with all wooded county locations, poison oak is a possibility, and there could be ticks here. Given the nearby playground, if you spot anything truly dangerous, like a Mountain Lion or a rattlesnake, report it - but you are far more likely to get a rare migrant warbler here than anything that dramatic.
The park maintains good bathrooms, picnic tables, and playground areas. Places for food, drink and provisions abound along El Camino Real. In fact, the park is walking distance from the Safeway Supermarket along El Camino Real, making it ideal for picnics.
The official phone number is 650-595-7441; the official address of the park is One Twin Pines Lane, Belmont, CA 94002
Twin Pines Park is an eBird hotspot, but it is lacking in data. Only fourteen of forty-eight time quadrants are represented. Take a noontime walk in Belmont, and contribute those sightings to eBird!
Sequoia Audubon Society has led one field trip to this darling park, in 2003.
