[2] The Ikersuaq fjord is oriented in a roughly NE/SW direction and to the southwest its mouth opens into the Julianehab Bay, Labrador Sea, North Atlantic Ocean.

There is a vast ice field on the northwestern side of the fjord, where there are three branches, Qaleragdlit Imâ, Kangerlua and Kangerluarsuk.

On its southern side the 1,440 m high Ilimaussaq peak rises in the peninsula to the east of the fjord.

Elongated Tuttutooq Island is a prolongation of the southwestern end of the peninsula forming the southern shore of Northern Sermilik.

The Narsaq Sound separates the peninsula from the island on the southern shore, connecting with neighbouring Tunulliarfik and Skovfjord.
