1. Tristan da Cunha
Located over 2,000 km (1,243 miles) west of Cape Town, South Africa, Tristan da Cunha is one of the most remote inhabited islands in the world. This volcanic island is only accessible by boat, and its isolation has allowed it to develop a unique culture separate from mainland society. With a population of around 266 residents, Tristan da Cunha is so far off the main shipping routes that even the occasional ship will often pass within 30 miles (48 km) without realizing it's there. The island's name comes from the Portuguese explorer João da Cunha.
2. Clipperton Island
Situated approximately 1,100 km (683 miles) northwest of Mexico City, Mexico, Clipperton Island is a tiny coral atoll with a maximum diameter of about 7 km (4.3 miles). The island has no permanent residents and is only occasionally visited by scientists or researchers. With an area of around 6 square kilometers (2.3 square miles), Clipperton Island is one of the smallest islands in the world, yet it still boasts a diverse ecosystem that includes sea turtles and over 100 species of fish. In 1969, the United States attempted to annex the island but it was ultimately returned to its French and Mexican owners. 3.Alert, Nunavut - Located on the northern tip of Ellesmere Island in Canada, Alert is one of the most northerly permanently inhabited places on Earth. This small Canadian hamlet has a population of just 5 residents during the summer months but can swell to over 100 people for the winter hockey season. With temperatures often dropping below -40°C (-40°F) in the winter and rising no higher than -12°C (10°F) in the summer, Alert is one of the most inhospitable places on Earth. Named after a Canadian admiral who died there in 1859.
4. Kerguelen Islands
Situated about 3,300 km (2,050 miles) southwest of Australia, the Kerguelen Islands are an archipelago that stretch for over 7,000 km² (2,700 sq mi). This French subantarctic archipelago has a unique ecosystem with no native land mammals and is considered one of the most pristine environments on Earth. With around 110 residents, mostly scientists at the France's Kerguelen Research Station, life there can be quite isolated due to the remote nature of the islands and its lack of connectivity.
5. Ittoqqortoormiit
Situated in Greenland, this small Inuit settlement is surrounded by vast, uninhabited ice sheet on three sides and a sea that is just 15 km (9 miles) wide. The population is about 500 residents but can swell to over 700 during the summer hunting season due to family reunions. Given its harsh climate with extreme cold in winter and temperatures often above -5°C (23°F) in the summer, this little town faces unique challenges such as lack of infrastructure and frequent loss of livestock to polar bears and other predators. Despite these difficulties, ittoqqortoormiit remains a thriving community that boasts stunning natural scenery surrounding it.
