As has been said, thin (or very thin) pickings are likely from the south side and the riverside path is a long walk from either rail access. By car it is possible to park right by the river in Lytham Crescent, Thamesmead SE28 8QH, which is fine for the tank farm opposite (where MILFORD FISHER is berthed at present), but east of there the berths are to a considerable degree obscured to south-side piers and barge moorings.
