How to get there - Go South over Hammersmith Bridge and turn left into Riverview Gardens. Free parking on Sundays & Bank holidays in road. (map)
Suggested Launch Site - There are short steps under the bridge and at intervals to east and west.
General
Description - Choose neap (minimum) tides and a start time to allow you to return to the exit point between high water and one hour after high water. After this time there may be too much current to exit safely dry. The trip to Kew bridge took my wife and I one hour in thermoplastic general purpose kayaks. Tidal information is available from the Met-Office "easytide" website.
Go upstream, with the tide. Cross the river with care to avoid larger craft and keep to the right hand side both ways in accordance with the Port of London Guide. The route passes under Barnes and Chiswick bridges, but these are not problems near high water. There are waterside pubs, but remember your exit time deadline. (route)
