Apolima is the rim of an extinct volcanic crater with a maximum height of 165 m. Its area is slightly less than one square kilometer. The only access to the island is by boat.
The tiny island lies 2.4 kilometres (1.5 mi) northwest off the westernmost edge of Upolu Island's fringing reef and 7 km (4 mi) southwest of the island of Savai'i. The island's shape is like an upturned bowl surrounded by steep cliffs. There is a broad opening to the sea on the northern side, which is the main entry point. Entry is only by boat.
In August 2022 the Ministry of Natural Resources and Environment began discussions with local residents about eradicating rats from the island to protect the local environment.
