Gelt Woods is a Site of Special Scientific Interest (SSSI) in the valley of the River Gelt. It is located 2km south of Brampton, near the village of Low Geltbridge in Cumbria, England. This protected area includes exceptional gorge woodland at a location where the River Gelt has cut through the New Red Sandstone. The area is protected because of the rare species of moss and liverworts and because of the diversity of woodland bird species. Part of the protected area is owned and managed by the Royal Society for the Protection of Birds.
