South Dock Marina is London's largest working marina, operated by Southwark Council and situated within South Dock and Greenland Dock on the south bank of the Thames — roughly 2. 5 miles downstream from Tower Bridge and 1. 5 miles upstream from Greenwich.

The marina offers over 200 berths, with locking in from the tidal river via a lock adjacent to Greenland Pier.

Originally constructed between 1807 and 1811 as the East Country Dock, the site is steeped in history and supports a variety of wildlife, including waterfowl. Despite its central London location, it is considered a tranquil haven.

Boats of up to 20 tonnes can be lifted on-site, and the marina is well connected by bus, Underground, DLR, and Thames Clipper river bus services from Greenland Pier.

Advance booking is strongly recommended, as berths fill quickly, particularly during high season.
