Bac Mòr

Bac Mòr is a small volcanic island in the Treshnish Isles off the coast of Argyll and Bute. Its Gaelic name means ‘large bank’ or ‘large obstacle’, and its shape resembles a cap. The island has no safe landing places, yet traces of summer sheilings show past use. A flat lava plain surrounds a central cone, the remains of an ancient volcano. The Treshnish Isles belong to the Hebridean Trust, a conservation charity. The island matters because the Treshnish Isles are a Site of Special Scientific Interest and a Special Protection Area. They host important seabird colonies and wildflowers. Bac Mòr’s volcanic past and uninhabited status help protect these habitats. The landscape offers stark contrasts between the dark lava and the green slopes. Visitors find a quiet, windswept island with few signs of human presence. The central cone rises gently above the plain, offering wide views of the sea. Seabirds nest on the cliffs and slopes. Wildflowers colour the ground in summer. The isolation and raw geology make it a place for careful exploration.
