The grounds of Gillies Hill have been used by walkers, joggers, birdwatchers, and botanists for decades. Geocachers from all over the world come to find no fewer than 40 geocaches hidden on the hill and in its immediate vicinity. Paths on the hill range from relatively easy rambles to more strenuous hikes. In the Winter paths can get slippery and muddy so it's best to come prepared with stout boots and a walking stick. Among the most popular walks are the Quarry Walk, the Lake Walk, the Tree Tour and the Public Trail that leads west through Murray's Wood to the Bannock Burn.
