A high rocky island with sea cliffs located mainly on the southern coast. The site also includes Kippakua small rocky island (15 ha) with sea cliffs on the northern and north-western sides, which slopes gradually to the south/south-west. The two islands were treated as separate IBAs in the previous international IBA inventory (Grimmett and Jones 1989): Kippaku (former site GL053) and Apparsuit (former site GL054).
Apparsuit supports the largest seabird colony in west Greenland. The IBA also holds 3,430-4,010 breeding pairs of Rissa tridactyla (1994 data).
