The Bight of Calormen was the first body of water from Narnia's coast, which was a huge bay that extended from the north eastern corner of the Wild Lands of the North to south eastern corner of Calormen.
Cair Paravel, Galma, Terebinthia, the Seven Isles, and the Lone Islands were islands of the bight. On the horizon line of Avra's (the third Lone Island) most eastern point was the most eastern point of the Bight of Calormen.
At the bight's most western point was the mouth of Glasswater. Caspian's voyage had begun in the Bight.
