A steep-sided dry stream valley on the edge of the Marlborough Downs near Swindon. Valued as flower-rich unimproved chalk grassland and traditional hay meadow. On entering the site visitors will glimpse a small spring fed stream bordered by hedgerow and old willow pollards. The stream separates the main valley from a colourful hay meadow. The site supports 23 butterfly species, and several uncommon plants which suggest the grassland has a long history of traditional management.
