River Westbourne and Grosvenor Canal

A guided walk of the lower reaches of one of London's major subterranean rivers. The walk starts off where the Westbourne river was once known as Bayswater Brook (Bayswater is a shortened version of Bayard's Watering Place, a place where bayards (horses) drank water from the river). En route you'll discover the alleyways and mews that once lined the river and the site of an ancient conduit which once supplied the city with water, natural ponds in Hyde Park, the encased river crossing a tube station and the spot where the sewer outfall empties into the Thames beside Chelsea Bridge. Booking via the website essential.
