A wooded summit in SE Stirling Council Area, Gillies Hill rises to 158m (518 feet) a half-mile (1 km) southwest of Cambusbarron and 2 miles (3 km) southwest of Stirling. It was from Gillies Hill that the servants, wives and children of Robert the Bruce's soldiers descended on 24th June 1314 during the Battle of Bannockburn. They were mistaken by the English army as reinforcements who took flight, giving the Scots victory. Considerably denuded by whinstone quarries, the hill became the centre of controversy in 2007 when the re-starting of quarrying operations was proposed. Local residents restaged the historic charge as a protest.
Wildlife found amongst the long-established mixed woodland includes red squirrels, peregrine falcons, buzzards and roe deer. There are rare Wellingtonia Firs and a Scots Pine which has been designated as one of Scotland's top 100 heritage trees. There are also the remains of an Iron-Age hill-fort.
