Just past the end of the Victoria line is a wild expanse most Londoners have no idea exists. Walthamstow Wetlands is the largest urban wetland in Europe, ten reservoirs spread across more than two hundred hectares, and since 2017 it has been free and open to the public.
The clever part is that it is still a working waterworks, supplying drinking water to millions of Londoners, so the wildlife and the reservoirs share the same space. The result is an extraordinary free haven for birds, herons, cormorants, tufted ducks, kingfishers and a pair of peregrine falcons that nest on an old water tower.
At its heart the old Victorian Engine House has been turned into a free visitor centre and cafe, and the brick Coppermill Tower gives a view over the whole watery sweep. Wide paths loop between the reservoirs, flat and easy, for a free morning that feels a very long way from the city.
Getting there: A walk from Tottenham Hale on the Victoria line, or from Blackhorse Road, with the main Engine House entrance on Forest Road.
Best time to go: Early morning for the birds and the still water, or autumn and winter when migrating wildfowl pack the reservoirs. Wrap up, it is open and exposed.
Insider tip: Climb the Coppermill Tower for the big view across all ten reservoirs, then watch the old water tower for the resident peregrines. Entry is free, only the car park is paid, so come by train and walk in.
