Boundary Bay Regional Park is one of Metro Vancouver Regional Parks' quiet treasures — a 260-hectare coastal park stretching along the east side of Tsawwassen, facing inland across the shallow waters of Boundary Bay toward the US border at Point Roberts. The park has two main components: the Boundary Bay Dyke trail (a 16-kilometre flat walking and cycling path that stretches from the Tsawwassen side all the way to Mud Bay at the Surrey border) and the tidal beach itself, which at low tide exposes kilometres of sand flats perfect for clam-digging, shell collecting, and long beach walks.
The park is internationally significant for migratory birds. Boundary Bay is a Ramsar-designated Wetland of International Importance, and the tidal flats host hundreds of thousands of migrating shorebirds each spring and fall — western sandpipers, dunlins, dowitchers, plovers, and the occasional rare peregrine falcon. The Western Hemisphere Shorebird Reserve Network lists Boundary Bay as a site of hemispheric importance. In winter, snowy owls regularly winter in the dyke grass — in some years dozens of them at once, which has made the dyke trail a bucket-list destination for BC birders.
For residents and newcomer families, the park is simply the best long-walk destination in the southern Metro Vancouver area. The dyke is flat, stroller-friendly, generally low-traffic on weekdays, and connects to Centennial Beach — a sandy bathing beach with a small café, washrooms, and a summer children's water park. The Mount Baker views from the dyke on a clear day are genuinely the best in Metro Vancouver.
How to get there
By car, take Highway 17 to 12th Avenue and follow east to Boundary Bay Road for the Centennial Beach entrance. By transit, the 620 bus from Bridgeport Canada Line stops near the park — about a 45-minute trip.
