The town is surrounded by the Stevenage Outer Orbital Path (STOOP), a circuit walk established by the North Herts Ramblers Group in 2008. The circuit provides an informal, active recreational leisure amenity readily available to the residents of Stevenage and the surrounding villages. The STOOP is split into several sections, accessible via a series of links from the town. The route passes through Graveley, Walkern, Beane Valley, Datchworth, Woolmer Green, Knebworth Park, St Ippolyts and Little Wymondley. It was launched on 20 September 2008.
