Stony Island
Stony Island is a tiny rocky islet off the coast of St Mary’s in the Isles of Scilly, one of the many small outcrops around the edges of the largest island.
Landscape
The islet is little more than a few square metres of granite and boulders, washed by the sea at high tide.
More about Stony Island

The coast of St Mary’s is fringed with small islands and rocks, several of them joined to the main island at low tide. They are good places to look for seabirds and seals from the coast path that runs around the island.
