The 20 Most Unexplored Places on Earth (14 Photos)

There are precious few places left on Earth where human feet have never stepped. The blank spots of medieval maps have been replaced by high-resolution satellite imagery, with explorers scaling the world's highest peaks and even descending into the depths of the Mariana Trench. Today, anyone can explore exotic locations like the Galápagos Islands in vivid detail with just a quick web search.

Yet pockets of pristine, untouched wilderness still endure. Year after year, scientists uncover newly discovered species of flora and fauna hidden within these uncharted corners. We’ve rounded up 15 of the planet's most intriguing places that will take scientists decades to fully explore.







Mount Namuli, Mozambique

Rising above the East African Plateau, these peaks are among the world's most mysterious and captivating landscapes. Much of the terrain is accessible only to seasoned rock climbers, leaving its ecosystem largely untouched to this day.





Javari Valley, Brazil

Home to at least 14 uncontacted Amazonian tribes, this remote region is one of the most isolated places on Earth—partly by law. Around 2,000 indigenous people live in complete autonomy from the Brazilian government within an area roughly the size of Austria. Their right to remain undisturbed is protected by a federal agency, with dedicated patrols guarding the borders against outsiders.



Northern Patagonia, Chile

Where temperate rainforests meet glaciers, fjords, and thermal hot springs, Northern Patagonia offers one of the most dramatic landscapes on Earth. As the least populated region in Chile, it remains difficult to reach, but the journey offers rewards like nowhere else.



New Hebrides Trench, Pacific Ocean

Located off the eastern coast of Australia, this deep-sea trench remained overlooked by scientists until late 2013. When researchers from the UK and New Zealand finally deployed robotic submersibles into its abyssal depths, they discovered entirely new species of deep-sea creatures never before seen anywhere on Earth.



Northern Forest Complex, Myanmar

Nestled on the steep slopes of the Eastern Himalayas, much of this subtropical forest has escaped human—and often destructive—encroachment. Hidden deep within the forests of Kachin State lies the world's largest remaining tiger population, alongside bears, red pandas, and rare species of gibbons.



Tsingy de Bemaraha, Madagascar

Spanning 600 square miles along Madagascar's western coast, Tsingy de Bemaraha is a vast, labyrinthine nature reserve where one could wander for months. It is home to an extraordinary number of endemic plant and animal species, and scientists believe countless others remain undiscovered. While the park's southern tip is open to visitors, most of its territory remains a strictly protected wilderness off-limits to tourists.



Namib Desert, Namibia

Its name literally translates to "a place where there is nothing." Dating back 80 million years—to the era of the dinosaurs—the Namib is one of the oldest and driest deserts on Earth. Despite its harsh conditions, life finds a way to thrive here. The desert is also rich in natural resources, harboring vast deposits of tungsten and uranium ores.



Star Mountains, Papua New Guinea

The crowning feature of this remote range in Papua New Guinea is the Hindenburg Wall—a sheer limestone cliff rising over a kilometer into a massive high-altitude plateau. Perched high above the lowland world, its ancient ecosystems have remained untouched for millennia. Recent scientific expeditions uncovered nearly 1,000 species of flora and fauna here, almost a hundred of which were entirely new to science.



Greenland

Although Norse explorers landed in Greenland as early as the year 1000, parts of its far north are still being mapped today. In fact, six uncharted, pristine islands off Greenland's coast were only discovered as recently as 1999. The vast majority of the mainland remains uninhabited, with roughly 80 percent of the island buried beneath a massive ice sheet.



Fiordland, New Zealand

Carved by ancient glaciers, Fiordland National Park is New Zealand’s largest national park. This breathtaking wilderness hosts a unique array of wildlife, including the takahē—a flightless bird once presumed extinct for over half a century. Today, Fiordland remains one of the wildest, most pristine expanses in the Southern Hemisphere.



North Sentinel Island, India

Home to the Sentinelese—an isolated tribe estimated at 50 to 400 people—this island remains almost entirely unmapped. The islanders fiercely resist any outside contact and have repeatedly repelled visiting research teams, preserving the island's mystery.



Sơn Đoòng Cave, Vietnam

Tucked away in Phong Nha-Kẻ Bàng National Park in Vietnam's Quảng Bình Province, roughly 300 miles south of Hanoi, lies Sơn Đoòng Cave. Speleologists discovered caverns reaching up to 200 meters high and 150 meters wide, crowning Sơn Đoòng as the largest cave on Earth. In sections where the roof collapsed long ago, sunlight streams in, nurturing a subterranean jungle complete with monkeys, birds, and insects.



Cape Melville, Australia

Located about 1,500 kilometers north of Brisbane, Cape Melville is a rugged wilderness that remains largely inaccessible except by helicopter. This remote terrain presents immense challenges for field researchers, yet new discoveries are made constantly—including three entirely new animal species identified during a single expedition in 2013.
