Mangersta Sea Stacks
Towering stacks of ancient gneiss rising from the Atlantic below the cliffs at Mangersta on the west coast of Lewis, reached on foot over rough ground.
On the far western edge of Lewis, beyond the beach at Mangersta in Uig, the land drops sheer into the Atlantic, and great stacks of rock rise from the water below.
They are made of Lewisian gneiss, some of the oldest rock on Earth at more than three billion years old, and the sea has been carving them ever since.
The largest is known as Am Buachaille, the Herdsman. On a wild day the waves thunder against the stacks and the spray rises up the cliffs; on a calm afternoon the low sun turns the rock gold. There is no visitor centre and no path signs to speak of, just a rough parking place for a few cars and a walk over boggy ground to the clifftop.
There are no fences or barriers, so take great care near the edge and keep children close.

Open at all times.
No fences; keep well back from the edge.
