Humans have left their mark on almost every scrap of the Earth's surface, from land to considerable portions of the oceans. But some places have remained relatively untouched by us, be it because of a hostile climate or remote location.

Click through the gallery to take a look at some of the most unspoiled destinations on Earth.

▲Visited and studied by Charles Darwin on the second voyage of HMS Beagle, the Ecuadorian islands are characterized by a wide variety of endemic species.

▲Marine iguanas, giant tortoises, sea lions, penguins, and whales all call the islands home at various times during the year.

▲The southern African nation is one of the least densely populated in the world.

▲It's home to a portion of the Namib Desert, where about a quarter of the world's cheetah population lives.

▲The archipelago located between the Norwegian Sea and the North Atlantic consists of 18 major islands.

▲It's most easily identified by the grass-roofed cottages found throughout the island's unscathed landscape.

▲Jonah Young, author of the book 'Southern Ocean: Oceanographer's Perspective,' has written that its berg-filled waters are "the most treacherous and dismal region on earth."

▲The author has also said that scientists have deemed its waters the clearest of any sea.

▲Located in the northwesternmost region of Argentina at the border with Chile and Bolivia, Jujuy is characterized by high plains with peaks reaching 16,400 ft (5,000 m) that descend into the Grand Chaco, a hot and semi-arid lowland.

▲The difference in height and climate produces desert areas, including salt mines.

▲This location in the country's Afar Region is possibly the hottest place on Earth, according to the BBC.

▲This surreal landscape can be seen at the Dallol Volcano, which despite its name is a hydrothermal field located 157 ft (48 m) below sea level. Its dazzling colors are a result of a combination of mud, salt, iron, and halophile algae.

▲Also known as taiga, this biome that circles the Northern Hemisphere covers 60% of the country’s land area. Yet, it remains vastly undisturbed.

▲The region is home to about 13% of Canada's population. The locals are highly dependent on the forest for economic activities.

This Himalayan nation in itself is a sparsely inhabited paradise. Now imagine how pristine its highest mountain might be!

▲

At 24,835 ft (7,570 m), Gangkhar Puensum is possibly the world's highest unclimbed mountain, according to the BBC.

▲Located in the country's Central Visayas region, the province is known for a number of unusual geological formations, particularly the Chocolate Hills (pictured).

▲The process behind the formation of these more than 1,260 hills is still a mystery, but many scientists stand behind the theory that they are the result of coral deposits paired with the effects of rainwater and erosion.

▲The Skeleton Coast is another Namibian location to make the list. Located on the country's northern coast, it was dubbed by Portuguese sailors as "The Gates of Hell" because of its harsh conditions, according to The Daily Beast.

▲Similarly, the region's native Bushmen tribes still call it "the land God made in anger."

▲

Part of the Northern Line Islands, this atoll is located south of Hawaii and is a territory overseen by the United States.

▲

The uninhabited land (aside from a handful of scientists and staff members) consists mainly of a reef, two shallow lagoons, and about 50 islets. It can't get much more pristine than that.

▲The highest of the Pakaraima range of tepui plateaus, Roraima defines the border between Venezuela, Guyana, and Brazil.

▲The mount, which is considered to be among the Earth's oldest geological formations, is also accessible to the experienced climbers or those willing to take a two-day hike up the mountain’s natural ramp-like path.

▲This Hawaiian island is the closest you'll get to understanding what the Aloha State looked like prior to colonization.

▲Nicknamed the "Friendly Isle," Molokai is the most rustic and the least populated of Hawaii's eight islands.

▲This national park located in the northwest region of Melaky is famous for its karstic plateaus, a terrain characterized by rocky ground and caves.

▲Stone Forest, as it's commonly known, is known for its rich biodiversity, boasting one of the world's most diverse wildlife, according to the BBC.

▲This ancient Orthodox monastery complex located at the border with Azerbaijan is comprised of about 15 monasteries, most of which long abandoned.

▲

Nestled on the semidesert slopes of Mount Gareja, the complex is a compilation of churches, chapels, refectories, and living quarters carved out of the solid rock.
