Boating through West India Dock entrance
West India Lock must be booked in advance. Availability is restricted to one hour either side of high water at London Bridge (minus roughly 20 minutes) between 7am to 4:30pm. Only where you have a confirmed berth or booked visitor mooring is there no charge. Plus, you'll need full salvage cover / wreck removal insurance to enter West India Dock.
