The George C. Reifel Migratory Bird Sanctuary on Westham Island is one of the best birdwatching spots in British Columbia and draws serious birders from across North America. Over 270 species have been recorded here, making use of the Fraser River estuary marshes, freshwater ponds, and managed wetland habitat. Peak season is October to April, when huge numbers of snow geese, Canada geese, ducks, and shorebirds fill the ponds and surrounding fields. In November, the snow geese alone can number in the tens of thousands.
The sanctuary has 3.5 kilometres of trails through dyke-top paths and reed beds, with viewing towers and feeding stations that allow unusually close views of waterfowl. Sandhill cranes stop over in autumn, and the resident great blue heron colony is visible year round. Admission is cheap. Bring rubber boots in winter — the dyke paths can be muddy.
