Thrunton Wood is an area of woodland and open moor in Northumberland. It is popular with walkers, mountain bikers and horse riders, and home to two waymarked walking trails.[1] [2] There is an Iron Age fort on Castle Hill, and Thrunton Wood is home to several caves, including Macartney's Cave, once home to a local monk, and Thomas Wedderburn's Hole, where a local highwayman reputedly once hid from the law.[3]
