Eden Gorge is a Site of Special Scientific Interest (SSSI) including a 5km length of the valley of the River Eden between Armathwaite and Lazonby in Cumbria, England. This protected area spans between the Settle-Carlisle railway track on the western side to Coombs Wood Forestry Commission site on the eastern side. The protected area includes 30m high cliffs where the River Eden has eroded through New Red Sandstone. The semi-natural woodland is apparently a remnant of the ancient Inglewood forest.
