Pacific Northwest Raptors is a bird-of-prey centre near Duncan, with hawks, owls, falcons, and eagles presented through close-up viewing and flight demonstrations. It is a good fit for the Cowichan Valley because it adds a wildlife stop between wineries, totem poles, and forest outings.
The strongest reason to visit is the demonstration format: seeing raptors move and respond is far more engaging than reading labels. Check the daily schedule before going, since the timing of talks and flying displays matters.
