Do You Usually Travel With the Same Airline... or Seek Out Different Worlds?

1. The Door to Hell

Darvaza Gas Crater, Turkmenistan

This massive desert crater has been burning continuously since a Soviet drilling accident in 1971.

2. The Eye of the Sahara

Richat Structure, Mauritania

This colossal, perfectly circular geological formation in the Sahara Desert is so vast, it's visible from space and its origin remains a subject of debate.

3. The Byzantine Rock Fortress

Monemvasia, Greece

This medieval fortress town is perched on a massive island-rock, accessible only by a narrow causeway, and completely car-free.

4. The Crooked Forest

Gryfino, Poland

Hundreds of pine trees in this forest grow with a mysterious 90-degree bend near their base, defying natural explanation.

5. The Chapel of Bones

Sedlec Ossuary, Czech Republic

This small Roman Catholic chapel is macabrely decorated with the skeletons of an estimated 40,000 to 70,000 people.

6. The Giant Crystal Cave

Naica Mine, Mexico

Deep beneath the Chihuahua Desert lies a cave system filled with the largest selenite crystals ever found, some over 10 meters long.

7. The Valley of Longevity

Hunza Valley, Pakistan

This secluded mountain valley is fabled for its incredibly long-lived inhabitants and pristine natural beauty, often called the real 'Shangri-La'.
