Thorney Weir – The Mets is a long-established carp fishery situated on Trout Lane in West Drayton, Greater London. The complex encompasses multiple lakes, including the Mets Lake and Thorney Lake, along with river stretches in the Colne Valley.

With a stock of more than 500 carp and a venue record exceeding 38 lb on the Mets Lake alone, it draws anglers seeking characterful, maturing waters rather than heavily managed commercial pools.

Access to the complex is controlled by fencing and natural boundaries formed by surrounding rivers, limiting entry to ticket holders. Day tickets are available on a self-service basis via an on-site ticket machine.

The site includes toilet facilities and an on-site bait and snack shop. Gates are locked overnight, with an emergency contact available for anglers needing access outside standard hours.
