One of the last surviving marshlands in London, declared a Site of Special Scientific Interest in 1985. Formerly grazed as common land, it was being cut for hay until cattle were reintroduced in 2003. These regimes encourage wild flowers and over 160 species have been recorded here.

One particular beneficiary of the grazing is creeping marshwort, which favours the grazed edges of ditches.

Reed warblers and sedge warblers nest in the reed beds, while snipe and stonechat visit in winter


On Lea Bridge Road between Walthamstow and Hackney. Park at the WaterWorks Visitor Centre or the Lee Valley Ice Centre on Lea Bridge Road (A104) and follow footpaths from there to reach the other sites.

Clapton railway station is about 10 minutes' walk from the Lee Valley Walk alongside the river, via Southwold Road. Regular bus services into London from Walthamstow and Leyton run along Lea Bridge Road.

Accessible at all times.

Summer for wild flowers, butterflies and other insects.
