The island is known for its magnificent deep fjords, floating icebergs, whale watching, distinct local culture, winter sports, and hiking. While the country is part of the North American continent geopolitically, the island forms part of Europe. It attracts tourists and scientists with its magical and stark Arctic beauty.

The second-largest island in Indonesia and sixth in the list of the world’s biggest islands, Sumatra is located west of Java and south of the Malay Peninsula in the northeast Indian Ocean. Straddling the equator, the island is prone to powerful earthquakes and tsunamis because it is positioned at the subduction zone of Indo-Australian and Eurasian tectonic plates. The island is known for its rugged tropical terrain, endangered wildlife, smouldering volcanoes, and rich forests. This is where you can catch a glimpse of some critically endangered species, such as the Sumatran tiger, the Sumatran orangutan, the Sumatran rhinoceros, and the Sumatran ground-cuckoo, while the picturesque beaches and clear barrels of the surf will lure you down to the sea. 

7. Honshu, 225,800 square kilometres (87,182 square miles)

Honshu Japan

Situated between the Pacific Ocean and the Sea of Japan, Honshu Island is considered to be part of Japan’s mainland. It is also the largest of the four islands of Japan, and home to some of the country’s major cities and cultural sites. Among the largest islands in the world, Honshu is the most populated and (and densely so) in the world. On the east coast lies the Japanese capital and megacity Tokyo, which itself is home to nearly 38 million residents. Lying southwest of Tokyo is the iconic, snow-capped volcano Mount Fuji, as well as its largest lake, Lake Biwa. Don’t forget to visit the city of Kyoto (situated at the centre of the island) known for its Zen temples, gardens lined with cherry blossoms, and traditional geisha.

8. Victoria, 217,291 square kilometres (83,897 square miles)

Victoria Island

The second-largest island in the Canadian Arctic Archipelago, Victoria is the largest island in the world to lie entirely within the Arctic Circle. Straddling the boundary between the Nunavut and the Northwest Territories of Canada, this fascinating island is the size of England and Scotland combined, but it is only the second-largest island in the Canadian Arctic. It also contains the world’s largest island within an island, within another island—Canada’s very own tiny “sub-sub-sub-island”.

Catch this nameless island that lolls across the centre of a small lake, which itself is encapsulated by a slightly larger island, which further resides inside one of a series of long lakes located 75 miles inland from the southern coast of Victoria Island. It was discovered by the Arctic explorer Thomas Simpson in 1838 and holds a population of less than 2,000. Get a glimpse of tens of thousands of caribou and musk-ox, both endemic to Canada.

The tenth-largest island in the world and the third-largest island in Canada, Ellesmere is considered part of the Queen Elizabeth Islands. It lies within the Canadian Arctic Archipelago and is also a part of the Qikiqtaaluk Region of the Nunavut province of Canada. As most of the island is covered by the Arctic Cordillera mountain system, it is the most mountainous island in the Canadian Arctic Archipelago and therefore, pretty inhospitable for its few human inhabitants. Only 146 people live here, and it wasn’t until 2011 that the first known circumnavigation of the island was completed. Jon Turk and Erik Boomer completed the 2,400 km trip by sea kayak which took them 104 days.
