This walk starts from the visitor centre and steadily climbs up to Mosshouse Reservoir, within the grounds of the Gnoll Estate Country Park. Recent felling work has opened up vistas of the area, providing fine views across the Neath Valley. The reservoir, built at the end of the 19th century, supplied water to the Neath town before being released as surplus to requirements by the Water Authority in 1982. It now provides a scenic destination before retracing your steps to the visitor centre, which has information on the area and a cafe .

Wildlife Watching: You may see Nuthatches in the Beech woodland. Daubenton bats roost here and often feed at dusk over the ponds, which are also home to the Common Frog.
