Stanborough Park, also referred to as Stanborough Lakes is a 126-acre (0.51 km2) park in Welwyn Garden City, Hertfordshire, England.The park features two lakes, which were opened more recently in 1970. They are man-made and were built as a result of gravel extraction at the time of the building of the A1(M) motorway, although the thought of a riverside park had been considered since the city's Master Plan of 1949.
