Even in the age of satellites and advanced technology, there are still places on Earth that remain untouched by human footsteps. These remote locations are either too dangerous, too inaccessible, or too protected for modern man to explore. From deep ocean trenches to hidden caves and isolated islands, here are 10 places on Earth that no one has ever visited.
1. Mariana Trench – The Deepest Place on Earth
The Mariana Trench, located in the Pacific Ocean, is the deepest point on Earth, reaching depths of about 36,000 feet. While submersibles have explored parts of it, vast regions remain uncharted due to the extreme pressure, darkness, and freezing temperatures.
2. Sandy Island, Australia – A Place That Disappeared
Sandy Island was once marked on maps between Australia and New Caledonia, but when researchers went looking for it, they found nothing but open ocean. The mystery of its disappearance has left scientists puzzled, and no one has physically set foot on it—if it ever existed at all.
3. Gangkhar Puensum, Bhutan – The World’s Highest Unclimbed Mountain

At 24,840 feet, Gangkhar Puensum in Bhutan is the tallest mountain that remains untouched by climbers. Due to local spiritual beliefs and government restrictions, climbing has been banned since the 1990s, leaving the mountain pristine and unexplored.
4. Vale do Javari, Brazil – A Land of Uncontacted Tribes
Located deep in the Amazon rainforest, Vale do Javari is home to the largest number of uncontacted tribes in the world. Due to government protection, no modern humans are allowed to enter, preserving this untouched wilderness for indigenous communities.
5. Son Doong Cave, Vietnam – A Hidden Underground World
Son Doong Cave is the largest known cave in the world, but many of its passages remain unexplored. Deep underground and filled with its own ecosystem, it’s a place where modern man has yet to set foot in its entirety.
6. Devon Island, Canada – Earth’s Closest Thing to Mars
Devon Island in the Arctic is the largest uninhabited island on Earth. Its harsh climate and barren landscape make it nearly impossible to explore fully. NASA even uses it for Mars simulations, but large portions remain untouched.
7. Surtsey Island, Iceland – A Forbidden Land
Surtsey emerged from the ocean after a volcanic eruption in the 1960s and has been untouched by humans ever since. Only a few scientists have been allowed to visit under strict regulations, making it one of the most pristine environments on Earth.
8. Yucatan Cenotes, Mexico – The Hidden Underwater Labyrinth

The Yucatán Peninsula is home to thousands of deep cenotes (sinkholes), many of which have never been explored due to their dangerous depths and underwater caverns. Some may even contain undiscovered Mayan secrets.
9. Antarctica’s Subglacial Lakes – A Frozen Mystery
Beneath Antarctica’s thick ice sheets, massive lakes such as Lake Vostok remain hidden. Scientists have drilled into them but have never physically visited due to extreme cold and inaccessibility.
10. Tepui Mountains, Venezuela – Isolated ‘Islands in the Sky’
These towering table-top mountains are so steep and isolated that entire species exist only on their plateaus. Many tepuis remain unexplored, hiding potential new discoveries in their untouched ecosystems.
Conclusion
Despite technological advancements, Earth still holds many secrets. These unexplored places remind us that nature can still outpace human curiosity. While some areas may one day be reachable, others will remain mysterious forever, serving as reminders of the unknown corners of our world.
