[1] The island, which is ice-free and oval shaped, 1.4 km (0.87 mi) wide by 1.7 km (1.1 mi) long, lies close off the south coast of the much larger King George Island, and marks the eastern side of the entrance to King George Bay.

It has a shoreline of low cliffs, with a beach on the north coast providing access.

There are two small black volcanic plugs visible in the red cinder cone crater.

[5] The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a wide range of seabirds including a breeding colony of over 600 pairs of southern giant petrels.

Other birds nesting at the site include Adélie and chinstrap penguins, Antarctic terns and kelp gulls.
