Brentford Dock Marina sits on the tidal River Thames at the confluence with the Grand Union Canal, between Kew Bridge and Isleworth in the southern part of Brentford, Middlesex.

Its position gives boaters direct access to the canal network as well as the non-tidal upper Thames, making it a versatile leisure mooring base in West London.

The site has a long working history: originally built in the 1850s as a transfer point for goods moving between Great Western Railway freight and Thames barges, it was redeveloped in the 1970s and is now a marina alongside a residential estate.

Lock keepers are on hand seasonally to assist with passage between the tidal Thames and the canal system.
