Cobblewave Cove is a large inlet south of Barmet Bay. It is surrounded by a pine barren and the sea itself is riddled with hidden rocks at this point. To the north of the bay is the beach Barren Sands.
The rocks hidden just below the surface combined with the rough seas make this area a danger to shipping. The wreck of the North Lines vessel Atlantis has been left there as a warning to other vessels.
