A map showing the location of the Sea of Dorne off the coast of Westeros.
The Sea of Dorne is a large inlet of the Narrow Sea in southern Westeros, separating Dorne from the Stormlands. The islands of Estermont and the Stepstones guard the mouth of the Sea of Dorne.[1]
In the books
In A Song of Ice and Fire, the Sea of Dorne is in the same location, bordered by the coast of Dorne to the south and the coast of Cape Wrath to the north. The coast of Dorne is craggy and difficult to land on, making invading the land by sea extremely difficult (although King Daeron I Targaryen did manage this during both of his attempts to conquer Dorne).
The castles of Wyl, Yronwood, the Tor and Ghost Hill lie on the Dornish coast, whilst Stonehelm and Mistwood lie on the Stormland coast. The Dornish maintain a prison on the tiny rock of Ghaston Grey, located just off the coast near the Tor. The prison's location makes it almost impossible to escape from.
