Immortalised by the great painters of the world -Canaletto, Monet- described by novelists -Dickens, Virginia Woolf- the Thames, a mark of London, traverses the city executing fanciful bends as it flows east to the sea. It can be approached on foot along the Embankment, a walk that Queen Victoria had built, but it is even better to sail up the river on a boat which can be taken at the pier at Westminster (Westminster underground) and take pleasure from a short trip east to Greenwich, a small village with a long maritime tradition, or to the south to Battersea and, with patience, to Kew and Hampton.
