Carsaig Arches, Natural arch formation on the Ross of Mull, Scotland.
Carsaig Arches are natural rock formations along the Ross of Mull coastline shaped by millions of years of coastal erosion. One arch resembles a railway tunnel opening, while another features a pyramidal rock mass with an unusual keyhole-shaped aperture.
These rock formations developed over millions of years through constant erosion of oolitic rock layers west of Loch Bay entrance. The geological process continues today as waves and weather gradually reshape the structures.
The name Carsaig comes from Gaelic roots that connect to the Scottish Highlands and their coastal identity. Locals and visitors see this place as a symbol of the raw Scottish coastline and its enduring relationship with the sea.
Access requires following a track from Carsaig Pier that takes about an hour to complete, so wear sturdy footwear. Plan your visit around low tide to safely explore the arches and rock formations without water obstacles.
A single basaltic pillar balances atop a pyramidal rock mass, creating an unusual geological arrangement rarely seen along this coast. This distinctive formation shows how different rock types work together to shape the landscape.
