For decades, trivia buffs believed that the largest island in a lake on an island on an island was a tiny island in a crater lake on Volcano Island in Lake Taal on the Philippine island of Luzon. But, exhaustive trolling of Google Earth has proved that to be wrong. Instead the distinction now belongs to a narrow strip of land in the middle of a massive lake in DR Congo.

Idjwi is the world’s ninth-largest lake island and Africa’s second-largest island in a lake on an island. It lies in the middle of the world’s largest freshwater lake and is part of the Democratic Republic of Congo’s South Kivu province. It measures about 70 kilometers (44 miles) long and drains naturally in two directions.

The world’s largest fresh water volcanic island is actually a complex of islands in a lake on an island in a lake. Ometepe is a complex of volcanoes on the lake of the same name in the Central American country of Nicaragua. Its natural drain is the lava-fed lake of Granada which separates the Concepcion and Maderas volcanoes on the island.

Ometepe is also home to the town of Moyogalpa which sits on a peninsula jutting out into the lake. It is the largest town on the island and offers a variety of hotels and restaurants. Those traveling to the island will likely begin their exploration in this area as it is the primary hub from which most activities on the island are conducted.
