Located on the rugged Gribun coastline of Mull, MacKinnon’s Cave is renowned as one of the deepest sea caves in the Hebrides, stretching for over 150 metres. Its dramatic entrance, reaching some 90 feet in height, hints at the vast chambers within. The walk to the cave is an adventure in itself, often involving a scramble over a boulder-strewn beach and muddy paths, requiring sturdy footwear and careful planning, as it’s only accessible at low to half tide.
MacKinnon’s Cave is steeped in local folklore and history. One of the most enduring tales tells of a piper who ventured into the cave, attempting to outdo the fairies in a piping competition. He was accompanied by his dog, but only the dog returned, crazed with fear and entirely hairless, suggesting the piper’s demise within the cave’s mysterious depths. Another legend states that Abbot MacKinnon, an early Celtic monk from Iona, sought refuge here in the 15th century to escape capture. Deep inside the cave, visitors can find a large, flat slab of rock known as “Fingal’s Table,” believed by some to have served as an altar for hermits or early Christian worshippers.
Geologically, MacKinnon’s Cave is carved into ancient Moine metamorphosed sandstones, with younger Triassic conglomerates and sandstones found higher in the cliff face. The cave’s impressive size and the varying rock formations within it make it a fascinating site for those interested in the island’s geological past. Its combination of natural grandeur, challenging access, and captivating legends makes MacKinnon’s Cave a truly significant and memorable destination for adventurous visitors to Mull.
