Prince Edward Island is much smaller (only about 45 km²) and lies some 12 nm (19 km) to the northeast. Prince Edward Island is located at 46°38′39″S, 37°56′36″E. At the Von Zinderen Bakker Peak northwest of the center, it reaches a height of 672 meters. There are a few offshore rocks along the northern coast, like Ship Rock (100 meters north of northernmost point) and Ross Rocks (500 meters from the shore).

Both islands are of volcanic origin. Marion Island is one of the peaks of a large underwater shield volcano that rises some 5000 m from the sea floor to the top of State President Swart Peak. The volcano was thought to be extinct, but broke out again in 1980 and is since classed as "active".
