Water Habitat

 

 

The Mimmshall Brook runs the length of the site on its way to Water End a few miles to the north. Here there is a group of fifteen swallow holes at the geological boundary between chalk and London clay, and the brook disappears underground. As it passes through Wash Lane Common, you may see a kingfisher or even a grass snake along the stream.

Please help us keep this park clean by putting your litter and dog waste in the bins provided.
