Humankind has left its mark on the entire land surface of the planet and a considerable portion of the oceans.

But some places have remained untouched by us, because of hostile climate or isolation. Here are some of the coolest unexplored places around the globe.

1.Vale do Javari, Brazil

This Region, home to at least 14 of the Amazon’s uncontacted tribes, is one of the most isolated places in the world. The tribes’ right to live in isolation is protected by a federal agency charged with preventing outsiders from invading indigenous territories.

2. Northern Patagonia, Chile

Home to temperate rainforests, glaciers, fjords, and hot springs, Northern Patagonia is one of Chile’s wildest landscapes. The Northern Patagonian Ice Field remains one of the immense masses of ice outside the polar regions.

3. Kamchatka, Russia

Russia’s eastern peninsula is home to some of the most spectacular volcanic activity on Earth. It’s home to the most diverse range of salmon species and is the most densely populated brown bear habitat in the world.

4. New Hebrides Trench, Pacific Ocean

Located off the eastern coast of Australia. Researchers from the U.K. and New Zealand sent underwater robots into this crack in the ocean floor almost four and a half miles deep, and they found prawns and eels totally unlike those found in other deep-sea trenches.

5. Northern Forest Complex, Myanmar

Many of the subtropical forests located on the steep slopes of the easternmost stretch of the Himalayas are virtually untouched by human activity. Deep within the woods in Myanmar’s Kachin State lies the largest tiger preserve in the world. It’s also home to bears, red pandas, and gibbons. 

6. Southern Namibia

The Namib is estimated to be the world’s oldest desert, and it’s one of the driest, least-populated places in the world. Dunes dominate the southern part of the harsh desert, and there are few paved roads.

7. Mount Namuli, Mozambique

This almost 8,000-foot-tall peak is the largest of a series of mountains that have developed much like separate islands, with very different species making their homes on the various peaks. 

8. Son Doong Cave, Vietnam

The world’s largest cave, which is 5.5 miles long, contains its river and even a jungle. Much of the surrounding network of over 150 caves near the Laos border remains unsurveyed. 

9. North Sentinel Island, India

Located in the middle of the Bay of Bengal off the southernmost tip of Myanmar, North Sentinel Island technically belongs to India. Still, few outsiders have made contact with the Sentinelese people. 

10. Star Mountains, Papua New Guinea

This remote region in western Papua New Guinea contains the Hindenburg Wall, a limestone network of plateaus more than a mile high. The 30-mile-long series of bluffs features nearly undisturbed ecosystems high above the ground. A recent biological survey of the area found 1,109 animal and plant species, almost 100 of which were new to science.
