One of the largest cave systems in Scotland, consisting of Fox's Den, Badger Cave, Bone Cave and Badger Cave. Unless you are and experienced caver with the right equipment only the first few metres of the caves can be explored. The caves were first explored by geologists in 1889 when bones were found in the entrance to the caves. There were excavations in 1926 which found bones which were between 8000 and 47000 year old, including bones which might be from a polar bear. See the SNH leaflet on Inchnadamph.
