Until they were closed in 1969 these filter beds were used to clean water taken from the River Lea for supply all over north-east London. After that nature took over and created, in a relatively small area, a mosaic of different habitats, including open water, reed bed, scrub, wet woodland and old brickwork.
Park at Lea Valley Ice Centre on Lea Bridge Road (A104). Follow the signs from the car park over the bridge and along the towpath.
Regular bus services into London from Walthamstow and Leyton run along Lea Bridge Road.
Accessible at all times
July–August for dragonflies and other insects.
