Walthamstow Wetlands is a 211-hectare site comprising ten reservoirs that provide drinking water for London and is the largest fishery in London. The wetlands are internationally recognised for their importance for migrating birds – particularly overwintering wildfowl. It contains a range of habitats and experiences, from sheltered dense scrub-lined banks to wide windswept views towards the city.
The Victorian-era Engine House hosts a fully accessible visitor centre with a café, shop, interactive displays, viewing platform, toilets, and art installations. In addition, a unique 'swift tower' has been built, in the shape of the original chimney, to house nesting swifts and roosting bats.
