King Arthur's Cave is a limestone cave at the foot of a low cliff at the north-western end of Lord's Wood in The Doward, near Symonds Yat, Herefordshire, about four miles northeast of Monmouth, in the Wye Valley. The cave entrance lies about 285 feet above the River Wye on a hill, with a double interconnected entrance and two main chambers. It is protected as a nature reserve under the Herefordshire Nature Trust. There is evidence that the cave was occupied by man during the Upper Palaeolithic era, and flint tools and woolly mammoth bones have been unearthed within and around the caves.
