The Torentine is a river in south-western Dorne. It flows out of the Red Mountains and into the Summer Sea. The castle of Starfall is located at its mouth, whilst the castles of High Hermitage and Blackmont are located further north along its banks.
In the books
In the Song of Ice and Fire novels, the Torentine is identified as one of the obstacles a traveller would have to traverse if they were trying to reach Oldtown if they were unable to use the Redwyne Straits (along with the burning deserts and rocky coastline further south-east).
