The bay extends from the point Kapp Traill to the south and northeastwards to the peninsula of Eggøya.
The only inhabited site on Jan Mayen, Olonkinbyen, is located at the plain Trollsletta at the southern part of the bay.
Further northeast is the shallow elongated lake Sørlaguna, which can extend up to eight kilometers in the spring, separated from the bay by the sandy bar Lagunevollen.
In the northeastern part of the bay is the shoal Nansenflua, named after the ship HNoMS Fridtjof Nansen, which was wrecked and sank after striking the rock in November 1940.
