Little Britain Lake, Cowley is within the Colne Valley Regional Park (OS Ref. TQ048813). It is located just east of the River Colne on the Greater London / Buckinghamshire border. London Loop footpath passes on the opposite side of the river and a footbridge leads to Packet Boat Lane. Access arrangements: by car from Packet Boat Lane, off High Road, Cowley Peachey (A408) or from Old Mill Lane, off Iver Lane (B470). Some parking space in Packet Boat Lane and Mill Road. Bus 222 (Uxbridge Underground Station to Hounslow Bus Garage) stops on the High Road near the Paddington Packet Boat pub and a quarter mile walk down Packet Boat Lane takes you to the lake. Recent improvements sensitively carried out by the London Borough of Hillingdon ensure that visitors can easily walk around the lake and have good views. Early in 2010 four tern rafts were provided - though not yet used by Common Terns. A public toilet at the junction of Old Mill Lane and Packet Boat Lane is a recent welcome improvement.
The lake sits between the rivers Colne and Frays.
There is a small heronry on the islands and reasonable numbers of winter wildfowl can be expected (including Gadwall and Shoveler). Great Crested Grebe have bred most years and Little Grebe is occasionally seen in the winter. Kingfisher can be seen on most visits. Ring-necked Parakeets are always around.
A footpath, Trout Lane, leads south and takes the walker to Yiewsley passing Yiewsley gravel pits (no public access, but visible from path).
Nearby birding sites include Thorney Country Park, the Colne Valley waters including Broadwater Lake, lakes at West Hyde and Stockers Lake.
