Starting from a free, public car park on the riverside near Ham House, we walked towards Richmond, over the bridge, back down the Thames to The White Swan pub at Twickenham. Lovely location and good pub food. I would recommend turning back for a short distance towards Richmond in order to cross the river via the ferry, returning close to the starting point. Alternatively continue on towards Teddington, which is mainly along the road and not very pleasant, crossing the Thames at the footbridge, and on back towards Richmond. Total distance 6 miles but only about 4 miles if omitting the Teddington loop.
