On Roche's path Geralt finds the entrance to this cave when he finds a drunken Odrin near the beach to the west of the Kaedweni camp.
If Geralt follows Iorveth's path, he climbs down into the same cave from the Vergen side, to reach the Nilfgaardian camp, looking for Triss.
The cave is haunted by many Rotfiends and two Bullvores. In one of the deepest chambers you can find the Armor of Ban Ard in a chest, guarded by a Golem.
