Slate Islands

Helping orphans the way you would do it
The Slate Islands are an island group in the Inner Hebrides, lying immediately off the west coast of Scotland, north of Jura and south west of Oban. The main islands are Seil, Easdale, Luing and Belnahua. Scarba, which lies nearby, is not usually included.

The underlying geology of the islands is slate, which was quarried widely until the mid-twentieth century. The Garvellachs lie immediately south west of the islands.
