The Bone Caves of Inchnadamph: Scotland’s Mysterious Limestone Caverns

Unearthing Ancient Mysteries in the Highlands

The Bone Caves near Inchnadamph are a remarkable geological and archaeological site formed from limestone cliffs on the northern face of Beinn an Fhuarain. First discovered in 1889 and extensively investigated in 1928, the caves gained their name from the wealth of animal bones found within. These remains include species now extinct in Scotland such as Eurasian lynx, arctic fox, brown bear, reindeer, and polar bear, dating back as far as 45,000 years to the Upper Palaeolithic era. While there is no evidence of permanent human habitation, human skeletal remains found in burial enclosures suggest the caves held ritual significance.

Geological Formation and Landscape Setting

The caves are part of a larger limestone cave system shaped by natural dissolution processes and the deepening of the valley over millennia. Positioned about 200 feet above the valley floor on Creag nan Uamh, the four main caves—Badger Cave, Reindeer Cave, Bone Cave, and Fox’s Den—are relatively shallow, about five meters deep, and just tall enough to stand in. Their elevated position offers breathtaking panoramic views across the rugged Assynt landscape, framed by snow-capped peaks and wild Scottish wilderness, making the journey to the caves as rewarding as the destination itself.

Exploration and Visitor Experience

Visitors can access the caves via a roughly 30-minute walk from the nearby NC500 road. The path ascends steadily through scenic countryside before becoming steeper and more challenging near the cliffs, with rocky steps and narrow ledges requiring careful footing, especially in wet or windy conditions. The caves themselves are dark inside, so carrying a torch is recommended. From within the caves, the dramatic window-like openings frame spectacular views of the surrounding highlands, creating a unique blend of natural history and scenic beauty. Warning signs caution about occasional rockfall, emphasizing the need for caution.

Scientific and Cultural Significance

The Bone Caves are invaluable to science, offering insight into Scotland’s Ice Age fauna and the climatic changes that shaped the region. The bones were likely washed into the caves by glacial meltwaters or used by animals for hibernation. The discovery of human remains in burial contexts adds a layer of cultural mystery, suggesting the caves were more than just animal shelters. Many of the fossils and artifacts excavated here are displayed at the Royal Museum of Scotland in Edinburgh, underlining the site's importance to Scotland’s natural heritage.

Local Environment and Conservation

Set within the wild and sparsely populated West Highlands, the Bone Caves sit in a protected natural environment characterized by limestone geology, peatlands, and moorland. The area is managed to preserve its ecological and archaeological value, with visitors encouraged to respect the fragile landscape. The site’s remote and rugged nature enhances its sense of adventure and discovery, attracting hikers and history enthusiasts alike.

Nearby Attractions and Amenities

The Bone Caves are conveniently located near the village of Inchnadamph and a short drive from Ullapool, making them an accessible highlight of the NC500 scenic route.
