Gillies Hill is home to many fine specimens of both broadleaf and coniferous trees, but two in particular stand out: a Scots Pine nicknamed The Big Pine, which has a girth of over 5.5 meters which makes it the fifth largest pine of this species in Britain - and the largest south of Perthshire; and a coppiced rowan of immense lower girth. These two trees, plus 16 additional trees on Gillies Hill are currently listed as Veteran Trees with the Woodland Trust's Ancient Tree Hunt Project. Also worth visiting is a row of massive, hollow but living, Sycamores that line the old road to the former site of Murrayshall west of the quarry.
