Boundary Bay is one of the most important migratory stopovers for birds along the Pacific Flyway, hosting thousands of shorebirds annually.
The park contains the Cammidge House, a heritage building constructed in 1911 that serves as a community and event space.
The extensive tidal flats are created by the deltaic sediments of the Fraser River, resulting in the characteristic shallow water.
The beach is part of a regional park system that preserves significant coastal marsh and grassland habitats.
During the summer, the park's dunes are protected to allow for the nesting and growth of fragile coastal vegetation.
Centennial Beach is the central feature of Boundary Bay Regional Park, situated on a shallow tidal bay that retreats significantly at low tide. The park encompasses the Cammidge House, a restored heritage residence, and offers expansive views of the Pacific Ocean toward the San Juan Islands. A network of walking trails connects the beach area to the surrounding marshlands and dunes, which serve as a critical migratory bird habitat. The on-site cafe provides seasonal refreshments for visitors using the park facilities. Shallow water depths make the area particularly popular for families during the summer months. The beach is part of a larger protected ecosystem within the Boundary Bay Important Bird Area. Parking lots are integrated near the main entrance to facilitate access to the shore and picnic zones. The beach area is characterized by sandy flats that are exposed for several hundred meters during low tide.

Check local tide tables before arriving, as the water recedes for a long distance during low tide.
Bring binoculars if visiting during spring or fall to observe migratory bird patterns in the wetlands.
Wear water shoes if planning to walk far out onto the mudflats, as the terrain can be uneven or soft.
Do not attempt to walk to the water's edge if a rapidly incoming tide is forecasted, as the water level changes quickly.
Park gates operate on seasonal hours; the park remains open year-round but facilities like the cafe are seasonal.
Stay on marked trails to protect sensitive dune vegetation and do not disturb shorebirds during migration periods.
