Martin, Dorne is partially inspired by Wales, Spain, and Palestine. It is ridden with cliffs, whirlpools, and hidden shoals, with few safe landings. The southern coast is some four hundred leagues long. There is another river in northern Dorne which flows near Yronwood to the Sea of Dorne, but its name is as yet unknown. The Wyl flows across the Boneway in northern Dorne to the Sea of Dorne. The Torentine has its source in the Red Mountains of western Dorne and ends at Starfall along the Summer Sea.

The Brimstone in southern Dorne flows past the Hellholt to the Summer Sea. The trading port called Planky Town is located at the mouth of the Greenblood along the Summer Sea. The major Dornish river is the Greenblood in southeastern Dorne, which is formed by the Vaith and the Scourge near Godsgrace.

The lords of House Vaith, for instance, are known as the Lords of the Red Dunes, while nobles of old who settled desert oases called themselves the Lords of the Wells. Eastern Dorne largely consists of dry, stony soil ill-suited for agriculture, while western Dorne contains deserts of red and white sand. Most of Dorne south of the Red Mountains is an arid wasteland.

Sunspear and the Water Gardens, both controlled by the ruling House Martell, are located in southeastern Dorne. The Prince's Pass leads to Nightsong, while the Boneway leads to Summerhall. There are two major passes, the Boneway and the Prince's Pass, which go through the Red Mountains to the Dornish Marches of the stormlands. Stretched between them is the mountain range known as the Red Mountains, which separates Dorne from the stormlands to the north and the Reach to the northwest and west. Dorne is bordered by the Sea of Dorne to the north, the islands known as the Stepstones to the east, and the Summer Sea to the south. The region is rocky, mountainous, arid and dry, and features the only desert on the continent.
