Located in the far north west of the AONB, Tindale Tarn is a good place to bird watch at any time of year in a highly scenic setting. A rich variety of breeding birds can be seen during spring and summer, including waders and black grouse. During the winter months, the Tarn attracts a range of wildfowl including wigeon and whooper swans. Heavily worked for zinc in the past, this area is also rich in industrial archaeology, including the remains of a quarry and smelter. The RSPB manages this site as part of their reserve at Geltsdale. An information centre is located at Stagsike Cottage which is accessible on foot. Disabled access by vehicle can be prearranged by phoning the reserve on 01697 746 717.
