Ellin's Tower Seabird Centre Holyhead, Anglesey. The South Stack reserve is very popular with visitors for many reasons. Visitor activity is concentrated around Ellins Tower (the RSPB information centre), where the paths are maintained to a higher standard than elsewhere on the reserve. The heathland areas and their network of paths are open to the public (on foot) at all times. These paths cross a mix of coastal and heathland terrain and some pass close to cliff edges. There are no specific RSPB trails, but the route of the Ynys Gybi circular walk and the Isle of Anglesey Coastal footpath are waymarked along with the routes of the public footpaths. The nature of the terrain makes many of the paths steep and rocky, making access difficult for anyone with impaired mobility. However, a well-surfaced, high-quality 2 m wide track with benches runs from the RSPB car park (complete with three disabled parking bays) into the heathland and onto a viewpoint in front of Ellins Tower. Access to Ellins Tower is via a steep flight of stairs. The permissive path through the farmland connects the two areas of heathland. This path is open to the public (on foot) at all times (except 10 December each year). Grazing animals are present, so please take care and keep dogs under close control. Access to the Isle of Anglesey Council's 'South Stack Island and the Lighthouse' visitor attraction is via approximately 400 steps of variable rise and tread width down the cliff (not part of the RSPB reserve).
