Gillies Hill is located in Central Scotland east of the city of Stirling and south of the town of Cambusbarron within the Bannock Burn and River Forth watersheds. A crag and tail formation, the hill rises gradually from an altitude of approximately 79 meters at the Bannock Burn Bridge at Sauchie Craig on its southern end to drop off in a series of crags (cliffs) - some natural, some the result of quarrying - at its northwest end at an approximate altitude of 160 meters.
