Rams Hill is an inconspicuous knoll of the Berkshire Downs (Berks. O.S. 6 in. XIX, NW. and NE.) on the ridge overlooking the Vale of the White Horse. It lies within the 700-ft. contour, with the ground sloping gently to the south and falling steeply to 400 ft. on the northern escarpment. To the west, a mile away, the land rises to White Horse Hill, a bluff over 800 ft. high, crowned by the hill-fort of Uffington Castle and with the eponymous turf-cut Horse on the westward slope slightly below.
The Ridgeway runs along the crest of the downs, south of Uffington Castle but on the north edge of Rams Hill, while along the bottom of the escarpment the Ickneild Way winds in and out of the coombes between the 400- and 500-ft. contours.
